Looks like this should be standardized. Either both raise TypeError, or both return a set. My preference would be TypeError, but that might be worse for backwards-compatibility.
{}.keys().union(set()) # 6
Seems to me that the pipe operator is staying on MappingView, so it's reasonable to add a corresponding ``.union`` to mimic sets. And intersection, etc.
{}.values() == {}.values() # 9 d = {}; d.values() == d.values() # 10
It's weird, but float('nan') != float('nan'). I'm not particularly bothered by this.
