There was a problem hiding this comment.
@Kha This issue was being masked by abstractNestedProofs. It was incorrectly abstracting the arrayMkInjEqSnippet since it was marked as def. So, it was not testing anything since the body was just an application after the abstraction step.

There is no rush to fix this one.

Good, because I don't know anything about pp.analyze :)

@semorrison I think the CI failed here. No feedback. |

I haven't seen that before, and I don't think it was related to my recent changes. Pushing an empty commit got it out of its stuck state. |

# PR contents This is the supremum of - #8284 - #8056 - #8023 - #8332 - #8226 (already approved) - #7834 (already approved) along with some minor fixes from failures on nightly-testing as Mathlib `master` is merged into it. Note that some PRs for changes that are already compatible with the current toolchain and will be necessary have already been split out: #8380. I am hopeful that in future we will be able to progressively merge adaptation PRs into a `bump/v4.X.0` branch, so we never end up with a "big merge" like this. However one of these adaptation PRs (#8056) predates my new scheme for combined CI, and it wasn't possible to keep that PR viable in the meantime. # Lean PRs involved in this bump In particular this includes adjustments for the Lean PRs * leanprover/lean4#2778 * leanprover/lean4#2790 * leanprover/lean4#2783 * leanprover/lean4#2825 * leanprover/lean4#2722 ## leanprover/lean4#2778 We can get rid of all the ``` local macro_rules | `($x ^ $y) => `(HPow.hPow $x $y) -- Porting note: See issue lean4#2220 ``` macros across Mathlib (and in any projects that want to write natural number powers of reals). ## leanprover/lean4#2722 Changes the default behaviour of `simp` to `(config := {decide := false})`. This makes `simp` (and consequentially `norm_num`) less powerful, but also more consistent, and less likely to blow up in long failures. This requires a variety of changes: changing some previously by `simp` or `norm_num` to `decide` or `rfl`, or adding `(config := {decide := true})`. ## leanprover/lean4#2783 This changed the behaviour of `simp` so that `simp [f]` will only unfold "fully applied" occurrences of `f`. The old behaviour can be recovered with `simp (config := { unfoldPartialApp := true })`. We may in future add a syntax for this, e.g. `simp [!f]`; please provide feedback! In the meantime, we have made the following changes: * switching to using explicit lemmas that have the intended level of application * `(config := { unfoldPartialApp := true })` in some places, to recover the old behaviour * Using `@[eqns]` to manually adjust the equation lemmas for a particular definition, recovering the old behaviour just for that definition. See #8371, where we do this for `Function.comp` and `Function.flip`. This change in Lean may require further changes down the line (e.g. adding the `!f` syntax, and/or upstreaming the special treatment for `Function.comp` and `Function.flip`, and/or removing this special treatment). Please keep an open and skeptical mind about these changes!
