This shouldn't raise TypeError:

>>> class RaisingBytes:
...             def __bytes__(self):
...                 1 / 0
... 
>>> int.from_bytes(RaisingBytes())
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 3, in __bytes__
ZeroDivisionError: division by zero

And yet CI is green. Am I missing something? I'm compiling your PR locally now to see what's going on.

Ah it's because you don't instantiate the class.
