Errors with map

[Avasam]

When trying to use the map class in a type stub, I get the following errors:

1. pytype.pytd.visitors.SymbolLookupError: Couldn't find map in some.module
   This can be worked around by importing map from builtins: from builtins import map

NotImplementedError: Can't convert <class 'pytype.pytd.pytd.Function'>: Function(name='builtins.map', signatures=(Signature(params=(Parameter(name='function', type=AnythingType(), kind=<ParameterKind.REGULAR: 'regular'>, optional=False,

Thanks for the report! Could you give an example of how you're using map that's generating this error?

Hi @rchen152 ! I hit this again in python/typeshed#11455
Here's a permalink to how it was used: https://github.com/python/typeshed/blob/2927d663dc054911b9954eb8356da531d073de2f/stubs/setuptools/pkg_resources/__init__.pyi#L97

And the associated GitHub actions run: https://github.com/python/typeshed/actions/runs/8073594519/job/22057530767?pr=11455

Unfortunately this time adding from builtins import map results in the following very long error to be repeated:
