Here is a (possibly frequently asked) question about this Moose thingy: Did someone ever write a "before moose/after moose" cheat-sheet-type list?
Background - I am very well versed in all the old-school perl OO techniques (including the horrific inside-out objects), I understand multiple inheritance and what MRO is and how e.g. C3 works. What puts me off in the Moose tutorials is all the CS-y terminology (role, trait, decoration, etc etc etc). Thus I am looking for some sort of map that can tie my existing knowledge with the "new way of doing things".
