Sometimes I use OOP in Perl, sometimes I don't. But then, sometimes I use Perl and sometimes I don't. The right tool for the right job and all that.

One thing to bear in mind is that OOP is a concept and NOT just a language feature. A prime example is GTK+ which is OOP written in C, which has zero support for OOP.

I dunno, do you feel that you can already use Perl to easily accomplish just about any task you want? If so, you can prolly study OOP in any language you want. If not, I would stick to Perl just so you can really develop an in depth knowledge of your first language. Not to mention that the details of learning the basics of the language will stay out of your way.

But please, if you're in this for the long haul, at least look at many languages. IMHO, any old programmer worth their salt should know at least half a dozen languages and especially C.

Oh, and just for the record, Perl is my favorite language because it is so expressive and I can bang things out in Perl way faster than any other language. On the other hand, Perl is useless for writing device drivers.
