- Make sure that `gset` and `mapset` do not bump the universe.
- Rewrite `tele_arg` to make it not bump universes. (by Gregory Malecha, BedRock Systems)
- Change `dom D M` (where `D` is the domain type) to `dom M`; the domain type is
now inferred automatically. To make this possible, getting the domain of a
`gmap` as a `coGset` and of a `Pmap` as a `coPset` is no longer supported. Use
`gset_to_coGset`/`Pset_to_coPset` instead.
When combining `dom` with `≡`, this can run into an old issue (due to a Coq
issue, `Equiv` does not the desired `Hint Mode !`), which can make it
necessary to annotate the set type at the `≡` via `≡@{D}`.
