There was a problem hiding this comment.
This error is not very helpful to users. Can we link the inference variable of the coroutine with the one of the unconstrained argument?

r=me with some improvement to the diagnostic or at least an issue open and linked from the tracking issue |

In the
ExprUseVisitor, we bail out when we encounter infer types. That means that the captures that we pass intoanalyze_coroutine_closure_capturesaren't actually lined up correctly, and we ICE. Turn this into a delayed bug.Fixes #123901
