in reply to High level OOP query

Typically, I initialize things immediately that aren't going to block my application (meaning, things that aren't CPU or memory intensive). Then, I lazily load everything else, either through setters, or even more lazily, when I want to persist something through a method call (say I have a save() method, I'll initialize whatever I need prior, then if I have an attribute that doesn't need to be set prior to calling save, say something like, retrieve_siblings(), which we will say hits a database, or something else that generates a thumbnail that hasn't been cached yet. That way you're calling it at the last possible moment and not creating a bottleneck in your application unnecessarily. Of course, this is a bit further down the road, there's no need for optimization until you've actually discovered slow parts in your code.

I also strongly suggest you learn how Moose and Moo work. They bring a sane object system into the Perl land and have some very, very good developers working on them.

    Moo/Moose later :)

    I think its better to first learn why/when/what/whichway ... and only later deal with mechanics/implementation/how-details like moo/moose/badger...bless

    Why yes, this is just an opportunity to link some new-to-me stuff I found :)

      I say Moose/Moo now, because that completely sidesteps the frustrations of having to figure out how to coerce native perl into doing OO. It's got a fairly standard OO syntax that you will be able to translate OO concepts into without too much hassle. Then, you can backtrack and learn how it's done with perl sans Moo(se) and it will make much more sense.

        Great point ... so you can write some Moo for OP?

        I think first pictures on paper, then Moo
