 # A corely symbolic language
 
 **Hi** is a programming language inspired by JavaScript, designed with a symbolic core to be more universal, AI-friendly, and conducive to code golfing. The syntax prioritizes symbols over keywords.
 
 The underscore \`_\` is the global output function.
 
-\`\`\`js
+\`\`\`javascript
 _("Hi world")
 \`\`\`
 
 ## Declaration and Assignment
+
 Variable lifecycle is split into two distinct symbolic operations.
+
 - \`:\` **Declaration**: Binds a name in the current scope.
 - \`=\` **Assignment**: Reassigns the value of an existing name.
-\`\`\`js
+
+\`\`\`javascript
 version: 1.0 // Declaration and initialization
 version = 1.1 // Assignment
 \`\`\`
 
-## The Block: Unifying Objects, Functions, and Classes
-The **Block** (\`{}\`) is Hi's foundational structure, unifying data objects and executable functions. Each Hi file itself is a block too. It is a sequence of expressions that can be invoked with \`()\`.
+## The Block: Unifying Objects and Functions
+
+The **Block** (\`{}\`) is Hi's foundational structure, unifying data objects and executable functions. It is a sequence of expressions that can be invoked with \`()\`.
 
 ### As a Data Structure (Object)
 A block can hold \`key: value\` pairs. A \`#\` prefix denotes a private property.
-\`\`\`js
+
+\`\`\`javascript
 player: {
   name: "Orion"
   #hp: 100
 }
+
 _(player.name) // "Orion"
 _(player.hp)   // -0 (null) because #hp is private
 \`\`\`
 
 ### As Executable Code (Function)
 Invoking a block with \`()\` executes its expressions. The value of the last expression is implicitly returned.
-\`\`\`js
+
+\`\`\`javascript
+// Simple invocation
 sayHi: { _("Hi") }
 sayHi() // Prints "Hi"
 
+// With parameters and return value
 add: (a, b) { a + b }
 _(add(2, 3)) // Prints 5
 \`\`\`
 
 ### As a Hybrid (Factory/Class)
-A block can contain both data and logic. The context symbol \`@\` refers to the current instance.
-\`\`\`js
+A block can contain both data and logic. When invoked, its internal declarations are re-initialized, making it a natural factory. The context symbol \`@\` can be used to return the newly created instance.
+
+\`\`\`javascript
 createPlayer: (name) {
   name: name,
   hp: 100
   @ // Return the new block instance
 }
+
 player1: createPlayer("Orion")
 _(player1.name) // "Orion"
+_(player1.hp)   // 100
 \`\`\`
 
+### Expression Separators
+Newlines act as implicit separators. Commas (\`,\`) or semicolons (\`;\`) are required for single-line blocks.
+
+\`\`\`javascript
+// Multi-line
+point: {
+  x: 10
+  y: 20
+}
+
+// Single-line
+point: { x: 10, y: 20 }
+\`\`\`
+
+## Arrow Expressions
+
+For concise single-expression functions, Hi provides the \`=>\` arrow syntax, inspired by JavaScript. It serves as a shorthand for a Block that immediately returns an expression, making it ideal for callbacks and functional patterns.
+
+It's a direct replacement for \`(params) { ^ expression }\`.
+
+\`\`\`javascript
+// Standard block
+add: (a, b) { ^ a + b }
+
+// Equivalent Arrow Expression
+add: (a, b) => a + b
+
+// Useful for functional helpers
+numbers: [1, 2, 3]
+doubled: numbers.map((n) => n * 2)
+_(doubled) // [2, 4, 6]
+\`\`\`
+
+## Booleans and Equality
+
+Hi dispenses with boolean keywords in favor of canonical numeric values for truthiness.
+
+- \`0\` is **falsy** (the canonical false).
+- \`!0\` is **truthy** (the canonical true, representing a logical NOT 0).
+- \`-0\` represents null/undefined values.
+- All other numbers, and any non-empty string, block, or array are "truthy".
+- The \`==\` operator performs strict equality comparison (equivalent to JavaScript's \`===\`).
+
 ## Conditional Expressions
-Hi uses a single ternary-like expression for all conditional logic.
-\`\`\`js
+
+Hi uses a single ternary-like expression for all conditional logic. The simplest form acts like a standard \`if\` statement.
+
+\`\`\`javascript
+// A simple 'if' to execute code conditionally
+status: "active"
+(status == "active") ? { _("User is active.") }
+\`\`\`
+
+You can provide an \`else\` branch using the colon (\`:\`) symbol to choose between two actions.
+
+\`\`\`javascript
+// if / else for choosing an action
+isOnline: !0
+(isOnline == !0) ? { _("Online") } : { _("Offline") } // Prints "Online"
+\`\`\`
+
+This structure is powerful because it's an *expression* that always evaluates to a value. The value of the executed block becomes the value of the entire expression, allowing you to assign the result directly to a variable.
+
+\`\`\`javascript
+// if / else returning a value
+result: (1 > 2) ? { "A" } : { "B" } // result is "B"
+\`\`\`
+
+Expressions can be chained to create \`if / else if / else\` logic.
+
+\`\`\`javascript
 // if / else if / else
 score: 75
 grade: (score >= 90) ? { "A" }
@@ -142,142 +234,257 @@ grade: (score >= 90) ? { "A" }
 _(grade) // Prints "C"
 \`\`\`
 
+If a condition is false and no \`else\` branch is provided, the expression evaluates to \`-0\` (null). 
+
+## Data Structures
+
+### Arrays
+Arrays are 0-indexed lists of values. They support random access via \`[]\` and are iterable.
+
+\`\`\`javascript
+primes: [2, 3, 5, 7]
+_(primes[0]) // Random access: 2
+primes[0] = 1        
+_(primes)     // Mutation: [1, 3, 5, 7]
+\`\`\`
+
+### Strings
+Strings are sequences of characters. They are immutable but support random access and iteration.
+
+\`\`\`javascript
+greeting: "Hi"
+_(greeting[1]) // "i"
+\`\`\`
+
+## Destructuring
+
+Destructuring provides an expressive way to extract data from Blocks and Arrays. The extraction operator \`->\` is used to unpack values, mirroring its use in module imports.
+
+- \`source -> { pattern }\`: Extracts properties from a Block.
+- \`source -> [ pattern ]\`: Extracts elements from an Array.
+- \`prop -> alias\`: The same operator is used within the pattern for aliasing.
+
+\`\`\`javascript
+// Setup
+user: { name: "Zeta", role: "Admin", id: 101 }
+coords: [10, -5, 8]
+
+// Extract 'name' and 'role' from the user block
+user -> { name, role }
+_(name) // "Zeta"
+
+// Extract 'id' and alias it to 'userID'
+user -> { id -> userID }
+_(userID) // 101
+
+// Extract first two elements from the array
+coords -> [x, y]
+_(y) // -5
+\`\`\`
+
 ## Repetition
-Repetition is handled by a unified iteration protocol: \`(source -> pattern) * { ... }\`.
-\`\`\`js
+
+Repetition is handled by a unified iteration protocol: \`(source -> pattern) * { ... }\`. This single, concise syntax adapts to iterate over any collection type.
+
+### Iterating Collections
+The \`->\` operator extracts elements from a source into a pattern.
+
+\`\`\`javascript
 // Iterate over an Array's values
 (["a", "b"] -> item) * { _(item) }
 
+// Iterate over an Array with index and value
+(["a", "b"] -> [i, item]) * { _(i + ": " + item) }
+
+// Iterate over a Block's key-value pairs
+({ id: 1 } -> [k, v]) * { _(k + " is " + v) }
+
+// Iterate over a String's characters
+("Hi" -> char) * { _(char) }
+
+// Destructure directly in the loop signature
+users: [{ name: "Orion" }]
+(users -> { name }) * { _("User: " + name) }
+\`\`\`
+
+### Numeric Ranges
+The \`..\` operator creates an iterable numeric range for concise, traditional loops.
+
+\`\`\`javascript
 // A range from 0 up to (but not including) 3
 (0..3 -> i) * {
   _("Iteration: " + i) // Prints 0, 1, 2
 }
 \`\`\`
 
+### Loop Control
+Control flow within loops is managed by distinct symbols:
+- \`><\`: **Break**. Immediately terminates the loop.
+- \`>>\`: **Continue**. Skips to the next iteration.
+- \`^\`: **Return**. Exits the parent block, not just the loop.
+
+\`\`\`javascript
+(0..10 -> i) * {
+  (i == 2) ? { >> }   // Skip 2
+  (i == 5) ? { >< }  // Break at 5
+  _("i is " + i)
+}
+// Prints: i is 0, i is 1, i is 3, i is 4
+\`\`\`
+
 ## Imports
-Modules are imported using the \`+\` and \`->\` operators, enabling context-aware autocompletion.
-\`\`\`js
+
+Modules are imported using the \`+\` and \`->\` operators. This allows for destructuring and aliasing of imported members. Placing the module source first allows development tools to provide immediate, context-aware autocompletion for the members being imported—a direct ergonomic improvement over JavaScript's syntax.
+
+\`\`\`javascript
 // Import 'block1' and 'block2' (as 'alias2') from a module
 + "npm://hi-lang@0.1/path/file.hi" -> { block1, block2 -> alias2 }
+
 block1()
 alias2("some value")
 \`\`\`
-`,
-            hib: `
-# .hib (Hi Block)
 
-The JSON equivalent for the Hi language.
+## Context Reference: @
 
-A \`.hib\` file is implicitly a Block; the top-level \`{}\` are omitted. It is parsed as native Hi syntax, allowing for comments, executable logic, and symbolic types.
+The \`@\` symbol provides a reference to the current execution context, similar to \`this\` in JavaScript. This allows a Block to refer to the object it was called on, making methods portable and reusable.
 
-### Example: \`theme.hib\`
-\`\`\`js
-// theme.hib
-// A .hib file can contain static data and dynamic logic.
-colors: {
-  primary: "#3498db"
-  accent: "#f1c40f"
-  text: "#2c3e50"
+\`\`\`javascript
+// This block is a portable method.
+// It relies on '@' to get the context.
+loggable: {
+  logId: { _("ID is: " + @id) }
 }
 
-// Expressions can generate data structures.
-// This creates an array: [0, 4, 8, 12]
-spacing: (0..4 -> i) * { i * 4 }
+user: { id: 101, log: loggable.logId }
+item: { id: "abc-789", log: loggable.logId }
 
-// A block that acts like a factory function.
-createRule: (selector, property, value) {
-  selector + " { " + property + ": " + value + "; }"
+user.log() // Prints "ID is: 101" (@ is 'user')
+item.log() // Prints "ID is: abc-789" (@ is 'item')
+\`\`\`
+
+## Expression Blocks and Fluent Chaining
+
+Hi adopts an expression-oriented design, similar to Rust. Every **Block** is an expression that yields a value.
+
+- The value of the *last expression* in a Block is implicitly returned.
+- To return early or explicitly, use the return symbol \`^\`.
+
+This makes code more concise by eliminating the need for explicit \`return\` keywords in most cases.
+
+\`\`\`javascript
+// The last expression, \`a + b\`, is returned.
+add: (a, b) {
+  _("adding...") // Side-effect
+  a + b         // Return value
+}
+
+result: add(2, 3) // result is 5
+
+// An early, explicit return
+check: (n) {
+  (n < 0) ? { ^ "Negative" }
+  "Positive"
 }
 \`\`\`
 
-### Usage in \`.hi\`
-The file is imported using the \`+\` operator.
-\`\`\`js
-// main.hi
-theme: + "./theme.hib"
+### Fluent Chaining
 
-_(theme.colors.primary)     // "#3498db"
-_(theme.spacing[2])         // 8
+To enable fluent method chaining, Hi adds one special rule: if the last expression in a block produces no value (e.g., an assignment), the block returns its own context (\`@\`) by default. This allows subsequent method calls on the same object.
 
-// Use the factory function from the .hib file.
-rule: theme.createRule(".title", "color", theme.colors.text)
-_(rule) // ".title { color: #2c3e50; }"
+\`\`\`javascript
+calculator: {
+  #total: 0
+  add: (n) { total = total + n } // Assignment has no value, returns '@'
+  sub: (n) { total = total - n } // Also returns '@'
+  get: { ^ total }               // Explicitly returns the final value
+}
+
+// .add() and .sub() return the calculator, allowing the chain
+result: calculator.add(10).sub(4).get()
+
+_(result) // Prints 6
