I don't know Forth, Perl, or even Rust enough to discuss them on that basis, but having other languages allowing it doesn't mean that C should be lenient about it either, or does it? Now, don't get me wrong, I do not dislike C, I've practiced it a lot, and I come back to it from time to time when I need to. But I would rather use a language where many of these forms are forbidden for readability and maintainability.
