Refactor (Maybe Coercion)
As discussed here: https://phabricator.haskell.org/D4395#inline-34607
Define a type
data MCoercion = MRefl | MCo Coercion
This is isomorphic to Maybe Coercion
but useful in a number of places, and super-helpful documentation. (eg MRefl
is much more perspicuous than Nothing
.
Define this in Coercion.hs
I think.
