bound, in the face of possibly multiple occurrences of the name. Using the
existing syntax you have to pick one rather arbitrarily, either the module
scope or the first place you find <name>.
(Again, I have never used nested functions, so this is more of a pedantic
argument than anything for me. Still, it seems if you're going to change
things you should make it so any instance of an outer variable can be
