Perhaps now key ordering has been pronounced we could either add a
"sorted" method to dicts equivalent to the following code.
def sorted(self):
return {self[k] for k in sorted(self.keys())}
Alternatively the sorted built-in could be modified to handle dicts in this
way. Though I still find the assumption of any ordering at all a bit weird
I suppose I'll grow used to it.
