I have tested against Coq 8.13 and Coq 8.12.1 this time around.

2. Support `⊂`
3. Support case splitting on `multiplicity x {[ y ]}`, but only do this when there's no other way.
With the improved `multiset_solver` I am able to solve pretty much all lemmas in the `gmultiset` file automatically (apart from those that involve `elements`, `size`, and other connectives that are out of scope).
The new version also handles @fpottier's test case `x ∈ X → {[x]} ⊆ X` from #86.
In addition, I added a bunch of other test cases.https://gitlab.mpi-sws.org/iris/stdpp/-/merge_requests/230coPset: some lemmas about infinity2021-03-05T21:02:23ZRalf Jungjung@mpi-sws.orgcoPset: some lemmas about infinityProofs by Joshua YanowskiProofs by Joshua Yanowskihttps://gitlab.mpi-sws.org/iris/stdpp/-/merge_requests/229clarify Pmap_raw comment2021-02-17T13:15:51ZRalf Jungjung@mpi-sws.orgclarify Pmap_raw commentMaking this an MR so @robbertkrebbers can check if it makes sense.Making this an MR so @robbertkrebbers can check if it makes sense.https://gitlab.mpi-sws.org/iris/stdpp/-/merge_requests/228Avoid relying on buggy simpl never behavior2021-02-12T13:33:42ZTej Chajedtchajed@gmail.comAvoid relying on buggy simpl never behaviorWhat's going on in this proof is that `simpl` is unfolding both `decode_nat` _and_ `decode`, even though `decode` is marked `simpl never`.
