GHC.Types.Unique.DSet

Specialised deterministic sets, for things with Uniques

Based on UniqDFMs (as you would expect). See Note [Deterministic UniqFM] in GHC.Types.Unique.DFM for explanation why we need it.

Basically, the things need to be in class Uniquable.

Like mapUniqDSet but for mapM. Assumes the function we are mapping over the UniqDSet does not modify uniques, as per Note [UniqSet invariant] in GHC.Types.Unique.Set.
