Didn't find any bugs here, but you really don't want these to fall out of sync.
Existing code could overlook types/substitutions that are embedded in (e.g.) an unevaluated constant.
In such a case, the `Infer` is converted to a `Bound`
Also, make `-Zverbose` dump all info about constants.

Is there a small regression test we could add here? |

I was wondering the same thing. The only way I observed this problem was in tandem with other changes that exposed it, but those changes can't be landed yet. |
