 ## The Block: A Unified Structure
 
-The \`{}\` syntax creates a **Block**, the foundational structure in Hi. A Block can be used as a function or an object.
+The \`{}\` syntax creates a **Block**, the single most foundational structure in Hi. A Block is a sequence of expressions that can represent data structures (like objects), executable code (like functions), or both simultaneously.
 
-### Function Block
+### As a Data Structure
-A Block with executable code is a function. Parameters are defined with \`()\`.
+When a Block contains named declarations (\`key: value\`), it behaves like an object. A \`#\` prefix denotes a private property. To support code golfing, expression separators are flexible:
+
+- **Newlines** act as separators. Commas or semicolons are optional.
+- **Commas (\`,\`) or semicolons (\`;\`)** must be used to separate expressions on the same line.
+
+\`\`\`javascript
+// Multi-line: separators are optional
+player: {
+  name: "Orion"
+  #hp: 100
+}
+
+// Single-line: separators are required
+player: { name: "Orion", #hp: 100 }
+point: { x: 10; y: 20 }
+\`\`\`

+### As Executable Code
+A Block containing executable statements can be invoked like a function. Parameters are defined using \`()\` before the block.

-### Object Block
+### Unification: Data and Behavior
-A Block with named properties is an object. A \`#\` prefix denotes a private property. Commas are optional between properties on separate lines.
+Since a Block is just a sequence of expressions, data and behavior can be combined seamlessly. This provides natural encapsulation without classes. Inner blocks inherit the parent's scope, allowing access to its state.
