Kyle Miller ce73bbe277 feat: detailed feedback on decide tactic failure (#4674) ... When the `decide` tactic fails, it can try to give hints about the failure: - It tells you which `Decidable` instances it unfolded, by making use of the diagnostics feature. - If it encounters `Eq.rec`, it gives you a hint that one of these instances was likely defined using tactics. - If it encounters `Classical.choice`, it hints that you might have classical instances in scope. - During this, it tries to process `Decidable.rec`s and matchers to pin blame on a particular instance that failed to reduce. This idea comes from discussion with Heather Macbeth [on Zulip](https://leanprover.zulipchat.com/#narrow/stream/270676-lean4/topic/Decidable.20with.20structures/near/449409870).		2024-07-11 20:08:29 +00:00
