Hmm... Can you explain a bit more about why rust-analyzer is encountering this but rustc doesn't? My only concern is that this filtering-out may instead hide bugs in the pattern lowering by silently filtering out patterns rather than exploding like it is now. |

The problem is that rust-analyzer regularly runs match checking on matches that aren't type-correct. They try to avoid that but their detection has holes. I'm not too worried about hiding bugs this way, because if an unexpected constructor shows up rustc should explode in |

ok thanks for the info @bors r+ rollup |
