I see.  Your use of "shadow" implies later "unshadowing", which can
only happen with scope.  Mine doesn't, I just associate "shadow" with
rebinding.  I think your usage is more accurate.  Especially in
Python, which has a much flatter (and more formalized) use of scopes
than, say, Lisp.

Thank you for your explanation, it helped (me, anyway).
