Wow, good diagnosis! This was happening in a test framework (using
unittest). I had a class which had a @staticmethod factory function, and a
class member dict where __init__() registered every instance of the class
that got created.
Something was going wrong, so in my test code (i.e. in __main__), I
imported the module directly and printed the dict. Lo and behold, it was
empty! As far as I could tell,
class Foo:
_map = {}
was getting executed again, which made no sense. I even went as far as
printing out id(Foo) in both places to make sure I really had the same
class (I did).
Thanks for the help. I never would have figured this out on my own.
