While i'm not a professional perl developer, but i bet yes; i saw them.

Then, have you seen my signature? ;=)

But look from another perspective: having or well using a module is a little price you pay, generally. If you use core modules, which every perl incarnation has ( http://perldoc.perl.org/index-modules-A.html ), the way is super plain: they are, for sure, better implemented than my or your code, they are tested a lot, they will remains stable during ages..

Normally a well desinged module push in just the code you want like in use List::Util qw(any); so you pay quite nothing.

CPAN is full, leterally, of useful modules too; here is preferable to choose carefully a well developped module, a famous and widely tested, or be able to understand what it is really doing: the risk to indroduce something unxepcted is present; with core modules is rare (by experience if i find something wrong with perl itself and it's core module i start looking for what i misunderstood about..).

Experimental features are by other hand to avoid unless playing with the language to learn.

I smiled the last time i was called Disci+ anyway; Discipulus is ancient latin word meaning pupil or student ;=)

PS: another good way to learn is creating an account on perlmonks.org asking and observing questions from others and their replies
