[New-bugs-announce] [issue16773] int() half-accepts UserString

[Serhiy Storchaka]

New submission from Serhiy Storchaka:

In Python 3 int() accepts UserString argument without explicit base and reject it with explicit base.

>>> from collections import UserString
>>> int(UserString('100'))
100
>>> int(UserString('100'), 2)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: int() can't convert non-string with explicit base


In 2.7 the same behavior also for MutableString and bytearray.
