I am beginning to feel a little stupid. :-(

Right... a decorator would always be called for a closure, not just once 
on module import. So I could make function "def parallel_for(iterable)" 
return a decorator and auto-execute the closure. That would indeed give 
cleaner decorator syntax instead of calling the decorated closure manually.
