Hello,

A minor semantic change that creeped in some time ago was an implicit assumption that any object x should "reasonably" be expected to compare equal to itself. The arguments are summarized below (should this be documented, inserted in NEWS, turned in a mini-PEP a posteriori ... ?).

I have to admit that I haven't done my research, but I think you have your history backwards: the recent change AIUI is that it's possible that 'x == x' might be something other than Py_True...

Cheers, mwh
