Macros

// Definir macro
macro_define("assert", ["condition", "message"], 
    "if not $condition then error($message) end")

// Usar macro
assert(x > 0, "x must be positive")

// Expandir
let expanded = macro_expand("assert", [true, "test"])

AST Manipulation

// Parse código para AST
let ast = ast_parse("let x = 1")

// Criar nó AST
let node = ast_node("Identifier", {name: "foo"})
let num = num(42)
let bin = bin("+", ident("a"), num(1))

// Walker AST
ast_walk(ast, fn(node) => print(node.type))

// Map transform
let transformed = ast_map(ast, fn(n) => 
    if n.type == "Identifier"
        then ast_node("StringLiteral", {value: n.name})
    else n
end
)

Compile-time Evaluation

// Avaliar em compile-time
let const_result = const_eval("1 + 2 * 3")  // 7

// Inline constant
let inlined = const_inline(42)

// Evaluate se constante
let evaluated = ct_eval(node)
