I hope I mentioned it was a hack? :)
It works for me, because I put spaces before if and while.

(font-lock-add-keywords
 nil `(("\\([[:alpha:]_][[:alnum:]_]*\\)("
        1 font-lock-function-name-face)) t)

could fix this particular issue.

Most likely the answer to such questions is:  Because nobody has
implemented it.

Doing it properly would probably require Emacs to parse the language,
which it doesn't.  And hacks such as mine fail on many borderline cases
like operator().
