Your example is misleading. Strings don't have an __int__:
>>> s = "3"
>>> s.__int__()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'str' object has no attribute '__int__'
Only int-compatible or int-coercible types (e.g. float, Decimal) should
have an __int__ method.
