Not at the interpreter level, but unlike dicts, sets are not used
much to implement interpreter logic. Their use cases are more based
in application code where you basically find two major use cases:

1. check for flag in set of numeric codes

2. check for string in unique set of strings

(and their associated set operations, i.e. checking for subsets,
superset, etc.)

This is why I don't follow Raymond's reasoning. Of course, if
he comes up with a patch that makes both cases faster, I'd be
+1 ;-)
