New submission from Robert Schuppenies <robert.schuppen...@gmail.com>:
Running this code:
>>> import weakref
>>> class C: pass
...
>>> ws = weakref.WeakSet([C])
>>> if ws == 1:
... print(1)
...
gives me the following exception:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/bob/python/svn/py3k/Lib/_weakrefset.py", line 121, in __eq__
return self.data == set(ref(item) for item in other)
TypeError: 'int' object is not iterable
Looking at _weakrefset.py line 121 gives
def __eq__(self, other):
return self.data == set(ref(item) for item in other)
which treats any 'other' object as a set like object. Therefore
comparing WeakSet to a non-set-like object always fails.
Do I understand it correctly and if so, is this the intended behavior?
