cc @rust-lang/compiler anyone can review this, I don't think it needs any special knowledge. I'd be grateful if anyone has the time. |

There was a problem hiding this comment.
Sounds like these should be kept as typeck errors and removed from resolve.

This looks good to me. I agree with @eddyb that reporting an error in the case of |

r+ modulo that question. |

Seems easy enough to change to only giving a type mismatch error in that case (I hacked the change and we didn't fail any tests). However the error message is a fair bit less informative and it seems tricky to add that information to the type mismatch error, so in this case I'd be in favour of leaving the duplicate errors (or trying to suppress the type mismatch, but that is trickier and best left as a follow-up). |

We can now handle name resolution errors and get past type checking (if we're a bit lucky). This is the first step towards doing code completion for partial programs (we need error recovery in the parser and early access to save-analysis).
I was thinking of trying to suppress the type mismatch, yes. OK. |
