I know I'm in a minority here, but I usually have problems with Perl documentation (in whatever form) first time out. It is seldom self-contained (frequently referring to something else in Perl you don't know anything about).

My advice on Perl OO (or Perl anything) is:

• read the documentation
• do the examples
• do something original with a knowledgable person in the vicinity for questions
• after a while, re-read the documentation; you'll get a deeper understanding of the topic, and because you've learned other Perl things since the first reading, you'll understand why you didn't get it the first time :)
