If you want to learn the use of OO in Perl and have time (say 2 to 4 weeks of evenings) to play:
- start with the perldocs perlobj, perlboot & perltoot to get an understanding of how the mechanics of OO works.
- Once you get bored with reconstructing those mechanics manually each time, do the Moose tutorial thing. (Another 2 to 4 weeks say.)
- Once you get fed up with the performance; you might decide that you don't need all the bells and whistles; and that actually, reconstructing the mechanics manually isn't so arduous after all.
If you want to understand the right way to think about problems, in a manner that will allow you to use OO effectively and maintainably, download an Eiffel compiler and splash out on Object-Oriented Software Construction, 2nd Edition by Bertrand Meyer.
Neither a cheap, nor easy, nor quick option, it will make you think about software and software development in a completely different way than if you acquire your OO knowledge in a piecemeal fashion. And you will never regret it.
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
