Message 404321 - Python tracker

Ah yes, I completely apologize about that typo, the __init__ is definitely needed (serves me right for trying to clean up a repo before posting it).

One other comment to make, perhaps obvious; manually passing a namespace to get_type_hints' `globalns` which contains `collections` does indeed solve the problem (in case anyone else sees this and is blocked). Of course determining the right values to pass is in general difficult for a user (and shouldn't be necessary).
