My example was poor, but my actual test code did't use 'not'. Python simply
checks the use of foo() to the local sig of foo() and does not go up the
chain. This is understandable and your next answer is more-or-less what I
was expecting.

Yeah. I guess I was hoping there'd be some clever trick to do it.
