|That keeps the semantics clean and consistent

That makes the semantics small, but might hinder polymorphism.

Besides, the iteration variable assignment already is quite complex
(and we are not going to fix them all), so that making part of them
"small and clean" does not make them consistent as a whole, I'm afraid.
