Well - maybe i'm wrong, but as i understand, 'more teorethical questions' are some kind proof of concept type. As far as for now i can't see a place to ask such questions and discuss possible solutions - although i think that many of us would learn a lot reading such sections.
in reply to New Section: Challenges?
++ for an idea and + for the name (for some 'challenge' might be just to understand what Perl is all about ;-P).
I think that 'Proof of concept' would be more suitable (even if it's much longer).
Sorry form my english - it's not my native language
