Re (tilly) 2: Determining if you have balanced delimiters

No, it works. It was supposed to do that. :-)

The idea is that it repeatedly matches a pair and removes it while it can. When it is done, it then checks if any were left over.

Well, in that case, it's another problem, since the dot can match the escape character, so it'll incorrectly blast "(\)". I knew it was something. {grin} -- Randal L. Schwartz, Perl hacker	[reply]

Did you test it? It recognizes "(\)" as unbalanced. OTOH he didn't bother to have an escape escape an escape. So "(\\)" is still unbalanced. But that could be a question of definition, not a bug.	[reply]
