As far as arbitrary floats hashing equally, I don't really care, but the simple ones definitely should. Hopefully at some point, "float constants" (as in coming from source code or user input) in Python will actually be Decimal representations, so you don't lose precision until you ask for it.

Should we expect this to work?

 d = {}
 d[Decimal('1.1')] = 1
 print d[float('1.1')]

Maybe pathological, maybe not.
