That depends a whole lot on what you intend to use Perl for. Nice thing about CPAN is that there are really good modules for most things you might want to do.

If you don't have a nice IDE and don't feel inclined to learn to use the debugger then Data::Dump::Streamer or Data::Dumper are good friends.

GetOpt::Long can save a bunch of time if you are writing command line based scripts and Tk is pretty good for quick and dirty GUI based stuff.

A quick trawl through a bunch of my scripts shows a pretty high hit rate for File::Find, Mime::Lite, Date::Manip, List::Util and a whole bunch more. I guess really, being able to use CPAN is the place where it's worth investing your initial time.

Perl reduces RSI - it saves typing
