[Python-Dev] default of returning None hurts performance? (original) (raw)

I fail to understand this crude logic.

If a function contains any looping (C or otherwise) or does much in
the way of meaningful work, then it's unlikely that the single POP_TOP
associated with an implied "return None" is taking much of the total
runtime.
