(BTW: I now understand why you changed the subject altogether, since, with reference to use Perl; again, people -including me- do that all the time there. But here it's generally discouraged. In fact I'm surprised no one complained: it is commonly recommended that if you do so, you also keep some track of the previous subject in the new one. This is especially intended for searching purposes.)
Yes, and I find it absolutely astounding that rather than fix the search feature so that it can deal with subject line changes, the masters of perlmonks prefer to send nag messages to people who dare to change their subject line.
(My personal opinion is that this makes them seem like a bunch of noobs who just discovered the internet yesterday -- changing the subject line to match the actual subject under discussion has been one of the basic principles of netiquette for about as long as the net has been around.).
