This PR allows fixing regressions in mathlib introduced in nightly-2024-02-25 by allowing the use of `x * y` in match patterns. There are currently 11 instances in mathlib explicitly flagging the lack of this match pattern. This issue was previously pointed out in the following Zulip threads: - https://leanprover.zulipchat.com/#narrow/channel/287929-mathlib4/topic/Algebra.2EFree/near/321482426 - https://leanprover.zulipchat.com/#narrow/channel/270676-lean4/topic/match_pattern.20attribute.20on.20Mul.2Emul/near/321505298 - https://leanprover.zulipchat.com/#narrow/channel/270676-lean4/topic/.40.5Bmatch_pattern.5D.20for.20basic.20binary.20operators/near/423734085 - https://leanprover.zulipchat.com/#narrow/channel/270676-lean4/topic/Mul.20match_pattern/near/430635623 |
