There was a problem hiding this comment.
I can revert that part if you like -- I was actually working towards a goal with this patch series that didn't work out, so it's not really important either way (I just figured I'd land some of the incidental changes).
That said, I always get annoyed that enter gives me ownership of an InferCtxt, when almost everything wants a reference. I'd be quite surprised if the indrection around Inherited cost performance.

Sigh. I should really rebase this. |

Ping from triage, @nikomatsakis ! We agree you should rebase this ❤️. Might as well respond to the review feedback you got while you are at it! |

Eh. I don't care enough to rebase this. =) |

Just a few small simplifications.
