Coverage for tests/fixtures/inheriting_typing_NamedTuple.py: 100.00%

1""" 

2While recursing on a class inheriting from `typing.NamedTuple`, the class' `__dict__` returns items 

3that are identified as properties. 

4 

5When trying to get the signature of these properties' `fget` methods, 

6`inspect` raises a `ValueError: callable operator.itemgetter(0) is not supported by signature` error. 

7 

8Instead of failing, we simply set the signature to `None`.
