I suspect not. Maybe with fromAscList or fromDistinctAscList so it can know
the list won't pop a smaller (here, duplicate) value on it, if it's lazy
enough (I haven't checked). Lists don't record that they were generated
from enumerations.

The following expressions both cause GHCI to hang:
S.intersection (S.fromList [1,2]) (S.fromList [1..]) fromList ^CInterrupted. S.intersection (S.fromList [1..]) (S.fromList [1,2]) fromList ^CInterrupted.
Is there a smarter way to take the intersection of sets when at least one of them is small (but I don't know which one that is)?
