Aaron Liu 5c8ebd8868 feat: make Option.decidableEqNone coherent with Option.instDecidableEq (#9302) ... This PR modifies `Option.instDecidableEq` and `Option.decidableEqNone` so that the latter can be made into a global instance without causing diamonds. It also adds `Option.decidabeNoneEq`. See [Zulip](https://leanprover.zulipchat.com/#narrow/channel/270676-lean4/topic/Option.2EdecidableEqNone/near/527226250). --------- Co-authored-by: Eric Wieser <wieser.eric@gmail.com> Co-authored-by: Rob Simmons <rob@lean-fro.org>		2025-11-20 01:48:42 +00:00
