Also look into picking up Damian Conway's book "Object Oriented Perl":
which is both witty and informative.

What I like to do is look at my code and think "6 months down the road
am I going to remember that $info{name}{date} is the purchase date?" and
the answer is usually no.  Or "If someone else took over this project
can they easily extend what I've done?" -- if all you have are one off
scripts then no.

When you start writing modules you might think that you're doing a lot
of work for little gain.  Why am I writing all these getters and setters
when it took me 2 seconds to think up $info{name}{date}?  Keep reminding
yourself that you *read* code 100x more often then you *write* it.  So
if it takes you an hour to write a good module it will pay off in the
long run as you don't have to keep on remembering what data structures
you were using.

Good luck!
