[issue11854] __or__ et al instantiate subclass of set without calling __init__

[Raymond Hettinger]

Raymond Hettinger <raymond.hettinger at gmail.com> added the comment:

If some code were added to call __init__ for the new instance of a set/frozenset subclass, it would have to make an assumption that the method's signature allowed it to be called without any arguments.
