The Mapping ABC's __eq__ method should return NotImplemented if the other type is not a Mapping, to give the other type a chance at the comparison. Right now it simply returns false. The comparison methods on the other ABCs in _abcoll.py already return NotImplemented if they don't recognize the other type. |

A test would be good. |

Backport to 2.6 and 3.1? |

Yes, I think this is a good candidate for backport. The ABCs are new and their APIs shouldn't contain any obvious bugs such as this. |

Here's a patch that adds test cases. It exercises all of the following special methods on Set and Mapping to ensure that they return NotImplemented if they don't recognize the other type.
lt, gt, le, ge, eq, ne, or, and, xor, sub
I made the patch against the py3k branch.
I made the test-case patch separate to make it easier to see the before and after behavior of the actual fix.
