I'm trying to write a programmer's guide to object oriented perl. Object Oriented Perl looks very similar to
C++, but only superficially. The underlying mechanisms are very different -- in fact they very much resemble an afterthought. I am still grappling with it, but I plan to write out a learn-as-you-go report that people may find useful.
You can read W0lf's Guide to Object Oriented Perl for C/C++ Programmers, here.
