New submission from Aidan Clark :
[I believe this is fundamentally a dataclass version of
https://bugs.python.org/issue41249]
When using `from __future__ import annotations`, calling get_type_hints on the
constructor of a dataclass B which inherits from a dataclass A defined in
another
Aidan Clark added the comment:
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`
