- Unique set type
  - Manipulating these sets

Description

Specialised deterministic sets, for things with `Uniques`

Based on `UniqDFM`s (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.
