Why doesn't this work? >>> from weakref import ref >>> class C(str): pass ... >>> ref(C()) Traceback (most recent call last): File "<stdin>", line 1, in ? TypeError: cannot create weak reference to 'C' object >>>
Note that this does work: >>> class D(int): pass ... >>> ref(D()) <weakref at 0x53e10; dead> >>> Likewise for floats, lists, etc. Everything but strs. rg -- http://mail.python.org/mailman/listinfo/python-list
