No Rewrite For Exit

Since PHP 8.4, exit() is also a function, and may be called as such.

Yet, it is still a PHP keyword, so it cannot be used as a function name: this would allow creating functions with that name in namespaces. On the other hand, it is possible to use that name as a method name.

And it is also not possible to use exit in a use command: that would allow rewriting exit with another function.
