There are a couple of places in Mathlib where we'll need to replace have p : x ∈ ⊤ := Set.mem_univ x with have p : x ∈ (⊤ : Set β) := Set.mem_univ x.

Is this unavoidable collateral damage?

There is still fallout in Mathlib. Let's not merge this until I've had a chance to look a bit further through this.

@semorrison Could you please create a mwe for this one? It is useful to have it in our test suite.

feat: add withSynthesize (postpone := partial) k

It forces pending elaboration problems and tactics to be executed, but
allows TC ones to be postponed.

@semorrison I pushed a fix, but did not manage to test because of a linter failure in Mathlib.

feat: backport changes from lean-pr-testing-4096 (#12772)
b72ddd8 
These changes will be required after leanprover/lean4#4096, but they all look like positive readability changes to me anyway (the things being filled in are sort of hard to work out with time travelling to later lines in the proofs!), so I think we can backport them all to `master`.
