- `while <condition> do <body> end`; the conditional block lives between `while` and `do` and re-runs every iteration.
- `n for ... end`; the loop count is popped, stored on the return stack, and decremented each pass. The compile-time word `i` exposes the loop index inside macros.
- `label name` / `goto name` perform local jumps within a definition.
- **Text macros** – `macro name [param_count] ... ;` records raw tokens until `;`. `$1`, `$2`, ... expand to positional arguments. Macro definitions cannot nest (attempting to start another `macro` while recording raises a parse error).
- **Text macros** – `macro name [param_count] ... ;` records raw tokens until `;`. `$0`, `$1`, ... expand to positional arguments. Macro definitions cannot nest (attempting to start another `macro` while recording raises a parse error).
- **Struct builder** – `struct Foo ... end` emits `<Foo>.size`, `<Foo>.field.size`, `<Foo>.field.offset`, `<Foo>.field@`, and `<Foo>.field!` helpers. Layout is tightly packed with no implicit padding.
- **With-blocks** – `with a b in ... end` rewrites occurrences of `a`/`b` into accesses against hidden global cells (`__with_a`). On entry the block pops the named values and stores them in those cells; reads compile to `@`, writes to `!`. Because the cells live in `.data`, the slots persist across calls and are not re-entrant.
- **List literals** – `[ values ... ]` capture the current stack slice, allocate storage (`mmap`), copy the elements, and push the pointer. The record stores `len` at offset 0 and items afterwards so user code can fetch length via `@` and iterate.
