I saw all that `PHP_FUNCTION` and `ZEND_PARSE_PARAMETERS` so thought that
was just a regular exposed function with compilation toggled by setting.
Anyway doing it directly in the lexer would avoid the argument parsing step
(and turning parentesis optional).

This can be useful for testing frameworks which does contract programming
by assertions but only in development.
