Hi all,
I have noticed there is a slight asymmetry in the way the interpreter
(v3.3.5, reproduced also in v3.5.x) loads and stores globals. While
loading globals from a custom mapping triggers __getitem__ just fine,
writing seems to silently ignore __setitem__.

The request is for a class within timeit that allows you to test code

Thank you Greg. Your second approach works and the script became:
That's not really what I meant; doing it that way,
you're still incurring the overhead of a tk canvas
