And if it was, wasn't it mine to waste anyway?
Don't be silly! You cannot judge how to waste your time. The accepted Perlmonks mores is that reinventing anything that's already on CPAN is bad, because the mere act of uploading code onto CPAN, makes the code awesome and the author a demi-god(dess). Reusing anything that wasn't written in Perl is horrible, one should always, without exception, prefer something written in Perl over a tool that has been improved over the past 40 years. Only people intended to destroy the Perl culture would use
system.
