Thanks for giving this some time. I think that backwards compatibility should be a higher priority than being able to issue -3 warnings -- if the warnings can't be generated, too bad, we'll just have to document it. (I don't think that checking things at class scope is an easy task in 2to3, though I may be underestimating it.) So, concluding, insofar as the proposal is to revert 2.6 to the 2.5 semantics where it comes to __eq__ and __hash__, I'm okay with that if there's no other way to maintain backwards compatibility, even though my preference would be to still flag this when -3 is specified. (There may be similar backwards compatibility issues caused by stricted arg checking in __new__ and __init__ -- the same remarks apply there.)
