I've written about closures in Perl here: * http://perl-begin.org/tutorials/perl-for-newbies/part3/ And there's a lot of stuff about them in Higher Order Perl: * http://hop.perl.plover.com/ I've truly understood what they were all about after I read the book "Structure and Interpretation of Computer Programs" (which uses Scheme for its examples): * http://mitpress.mit.edu/sicp/ All of these resources are available online.
