`QuantifiedContexts`?
That's up to you. At some point (be it now or after `QuantifiedContexts`
is a thing) I'd like to have a ticket for modifying
`GeneralizedNewtypeDeriving` to infer quantified `Coercible` constraints.
I'd be fine with either making this the ticket for that feature, or for
closing this in favor of a different one.
