I noticed the docs for DA.Next.Set are a bit sparse, and wondered if they could be expanded. `difference`'s docs don’t really tell you what operation it performs, it would be good to give an example, particularly since I would guess its operation is not commutative, so knowing the order of the arguments is important.

Some better docs would definitely be great! I’ll make sure `difference` gets updated. We are also happy to accept PRs for this. The docs are in the same module as the code at [daml/Set.daml at c8f31ca16ad2821caf768061c4fc65ce6666142f · digital-asset/daml · GitHub](https://github.com/digital-asset/daml/blob/c8f31ca16ad2821caf768061c4fc65ce6666142f/compiler/damlc/daml-stdlib-src/DA/Next/Set.daml)
