How about doubling-up the braces:

I mentioned that earlier. Its not *awful*, but as you point out yourself, it does run into the problem that nested sets suffer from brace overflow. # A set of sets. {{{{}}, {{1, 2}}, {{'a', {{}}, None}}}}
and for frozen dicts:
We don't even have a frozen dict in the stdlib, so I'm not going to discuss that here. If and when we get a frozen dict, if it is important enough to be a builtin, then we can debate syntax for it.
but how often would you do that?
