Comment (by goldfire):

 I'm with @bgamari here -- I see nothing unsettling about the original
 program. Note that GHC correctly identifies the pattern-match as non-
 exhaustive.

 Regardless of our opinions, writing up a [https://github.com/ghc-proposals
 /ghc-proposals proposal] is the official way to suggestions changes to the
 language GHC compiles. You may wish to do so.
