I will stick in simple named functions...

Simplicity is always a good goal and a good yardstick for judging your code. But I don't want to discourage you from using anonymous lexical subroutines: they work, and they work the way you think they work! In fact, Dominus wrote a whole book (freely available here — and highly recommended!) that's essentially just a zillion ways to use anonymous lexical subroutines.
