I know OO Perl, use it, but for fast code generation I use Class::HPLOO, than I convert it to a normal Perl Module and release it. This is about produce fast the code too!

Well, about the different groups, and teach, well, this is about money too, and time is money. They will learn OO Perl with the time, since they will start to work more with Perl. With Class::HPLOO, just from the begin I can count with their work, and my approuch is working, very well.
