You won't have used one because they have not yet existed (hence this
thread).

A frozen dict would also be useful but the implementation doesn't exist. If
it did exist then in combination with this proposal that syntax for frozen
dicts would be an obvious extension.
A more relevant question right now is if any other set syntax should apply
to frozensets e.g. should this work:
>>> squares = f{x**2 for x in range(10)}
