## Method Chaining ## Method Chaining
By default, a method call on a Block returns the Block itself (\`this\`), enabling fluent, chainable interfaces. To return a different value and break the chain, use the return symbol \`^\`. A Block's return behavior is designed for fluency. It implicitly returns the value of its last expression. If the last expression does not yield a value (such as an assignment), the Block returns itself (\`this\`) by default, enabling method chaining. The \`^\` symbol is used for an explicit or early return from any point in the Block.
