``` IDRIS2_VERIFY(cond, message_format, ...) ``` When condition is false, crash. Used in native functions where correct error handling is hard or not impossible. For example, `malloc` rarely fails, but if it fails, better crash with clear error message than spend time debugging null pointer dereference.
