Sorry for resubmitting an old regexp solution. Seems, that previous one disappeared. I have to solve this problem the proper way.

I think that this solution is perfectly legitimate. Why try to solve it "properly"? It's not like you are using eval or something like that. regexprep is a perfectly legitimate tool to use.

I agree with your point of view. Regexprep is a powerful function here.
Unfortunately I've used also '(??@some_code)'. In this case, it's not as bad as playing 'size=11' solution, but it is still a kind of size-cheating for me. I used to play solutions like that, but now I try to avoid this.
