New submission from Serhiy Storchaka:
The null character is allowed in __name__ setter (but error message is a little
confusing).
>>> class A: pass
...
>>> A.__name__ = 'B\0'
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ValueError: __name__ must not contain null bytes
But is allowed in type constructor.
>>> t = type('B\0C', (), {})
>>> t
<class '__main__.BC'>
>>> t.__name__
'B\x00C'
