Subject: More informative error when a global reference is used in a context
 of local variables which is a different from the one of its definition. E.g.:

Section A.
Variable n:nat.
Definition c:=n.
Goal True.
clear n.
Check c.

[I'm however unsure that "n" should not continue to be accessible via
some global (qualified) name, even after the "clear n".]
