Pick up a copy of Learning Perl (3rd ed, O'Reilly Press,
2001). It gives a good view of both OO and function-based
programming. If you're really into OO Damian Conway's
OO Perl is an excellent book -- both on OO in general and
Perl in particular.
Perl simplifies OO programming in two ways: The basic data
type is a high-level object and you don't have to entangle
the data and its behavior. The first saves you from spending
most of your time fiddling around with container classes
(scalars deal with numeric, string, etc, data by themselves).
Applying the classes as behavior simplifies the class design
and saves you from messy syntax common to most OO languages.
If you're seriously into OO check out Damian's Class::Contract
module. This implements an eiffel-type design by contract
interface. Nice thing is that it can be turned off in production
after the "contract" portion has done its real work. Gives you
the best of both worlds: Contract interfaces and good speed in
the real world.
