Was #109082 closed due to perf regressions? |

@fmease yes. Couldn't figure out how to mitigate them. |

When we have two types with the same name, one without type parameters and the other with type parameters and a derive macro, we were before incorrectly suggesting to remove type parameters from the former, which ICEd because we were suggesting to remove nothing. We now gate against this. The output is still not perfect. E0107 should explicitly detect this case and provide better context, but for now let's avoid the ICE.
