*Some* amount of code, sure.  Hard to quantify, but hard to believe there's
much code at risk.

Pythonic obviousness.  Virtually everyone coming to Python from other
languages *expects* visually nested functions to work this way.  That they
don't today is a very frequent source of surprises and complaints.
