This is too bad. There is a problem even defining what you want.
Assume we have a DictSet type:
After:
a = dict(a=1, b=2)
b = dict(a=2, b=1)
c = dict(b=2, a=1)
ds = Dictset([a, b, c])
What is len(ds)?
After those lines and:
c['a'] = 2
What is len(ds)?
After all the previous lines and:
a['a'] = 2
b['b'] = 2
What is len(ds)?
Making sets of mutable things is pretty useless.
You could make sets of tuple(sorted(adict.items()))
if the "adict"s don't have mutable values.
