The goal is to teach someone that the issues one generally runs into have been run into many times before. There is often a wheel that's round enough out there.
I guess our difference in opinion is where draw the line between "simple enough to do 'by hand'" versus "ok, this is hard, let's see if someone else has already done it better".
I'm not against modules, but I am against unnecessary modules. In this case, as I said, I found the use of a module overkill: instead of having a single regex that did a fairly simple task (and I could comment that regex further, but I didn't think it needed it), I now need to read and understand the documentation for the module. (And, in some cases, install it, make sure it's up to date, etc; File::Basename is a standard module, so that isn't an issue here.)
I once had a conversation with someone who thought a language (or, at least, a library / API) to generate regexes would be a handy thing to have. I disagreed, seeing as REs are already their own language; learning another one on top of the actual regex seemed unnecessary.
