pointer

pointer is a raw address into memory — the low-level type for runtime and foreign-function work, not something an everyday game reaches for. Allocate a raw byte buffer with bytes(count), which returns a pointer you index as buffer[index] to read or write one byte; retype the binding as words / fixeds / pointers to index in larger element sizes. A pointer is also how an extern function passes an opaque C handle across the ABI. Test one for emptiness against the null literal.
