Have you read MJD's "Coping with scoping?"


Closures are basically a trick of scoping. Variables are scoped in such
a way that they are "privatized" to an anonymous subroutine.

If you're having trouble with objects and references, I highly recommend
Damian Conway's book "Object Oriented Perl." I have very few computer
books that I didn't have to purchase for class: Knuth, K&R, and Conway.
