I built all of Stackage with this RC the other night and didn't observe any
regressions. Hooray!
(Thanks to Doug Wilson for helping me get set up with his
https://github.com/duog/build-stackage repo.)

Do TypeReps need to be cyclic?
No – I think David is working on a non-cyclic version

Subject: Re: Bringing some observable sharing t
Not being able to :print an exception would be quite annoying. Do TypeReps

Observable sharing can be done with StableName, but that would be a bit
pile of hassle in the printer. Maybe exceptions warrant a special case.

Re: let-bindings floating more easily, would a check for
`exprIsOkForSpeculation scrut` in theory suffice to float out cases?
Yes; but instead we simply turn such cases into lets.
