LGTM, assuming this shouldn't be an error.

AFAIR, "exotic" types in patterns produced errors some time ago, but maybe they do not now?

That is to say, I'm happy to either:

  1. Land this PR as-is,
  2. Make FnDefs in consts a hard error, guaranteed others also agree this is the right behavior (since this can happen only with unstable features, not sure if it necessarily even needs T-lang).

In don't see the place which @cjgillot is talking about in #114668 (comment), but let's make it an error for now.
