 See #10431.

 I'm compelled to ask whether there is more than one equality constraints
 in light of [https://youtu.be/hIZxTQP1ifo?t=2764 these]
 [https://www.reddit.com/r/haskell/comments/4w1jcr/using_typelevel_naturals_overloaded_strings_and/d63hgvk
 comments] by Edward and if `EqualityConstraint` were more apt (unless
 `~~`, `~#`, `~R#`, `~P#`, `Coercible` count)
