in reply to Dependencies, or, How Common is Regexp::Common?

Not very common I'd say. Besides, its Perl comment matcher is so simplistic it simply matches *any* # character to a newline.

    You must know more than I do. Are there Perl comments that aren't "start at #, continue to the end of the line"? Or are there any strings that if they follow a #, it's suddenly not a comment anymore?

    Note that $RE{comment}{Perl} matches just that, a Perl comment. It's not a parser that extracts comments from valid Perl code. All the regexes from Regexp::Common are context free. Anything that is context sensitive should be coded by the user.

      I think the poster was talking about something like this:

      print " # This is not a comment\n";

      Or that insane Acme::Comment module, but people who use that in a real program deserve what they get :)
