How do you expect your classes to be used? That's the big difference between the two approaches.

The first approach requires that I, your user, write a new class, test the whole class, and go forward from there. Lots of Perl knowledge required.

The second requires that I, your user, write a funciton and pass the subref to you in some constrained fashion. Less Perl knowledge required, but slightly messier design (from an imperative standpoint).

I personally prefer the second approach, because it's a better design for what you want to do. The extra time in design is well-worth the effort, IMHO.

Don't go borrowing trouble. For programmers, this means Worry only about what you need to implement.
