With freedom comes responsibility. Perl sets you free to program the way you want. If you abuse it you will pay. For example golfing down some code is fun but it doesn't lead to maintainable code.

I never use a CPAN module without first making sure that it is suitable for my needs. Most of the time the CPAN module works as advertised occasionally it doesn't. That's the beauty of Open Source. You trust no one. Always validate code you get from somewhere else. M$ languages on the other hand are take it or leave it. You can't validate their code because you don't have it. If there's a problem you can't check their code to see if that is causing it. You do it their way or you don't do it at all, at least in their view.
