Comment:

 I think this is a fine idea. It has a drawback in that it's not compatible
 with Haskell98 code, but perhaps that is not a deal-breaker. In any case,
 this kind of suggestion is perfect for the [https://github.com/ghc-
 proposals/ghc-proposals ghc-proposals] process, which I have found very
 valuable in understanding new ideas proposed for GHC (both as a proposer
 and as a reviewer of proposals). Feel free to copy and paste much of the
 text you have above, and don't worry so much about the fact that the
 proposal requires a "specification" -- your change is very simple to
 specify.

 In the meantime, I will close this ticket, as the community has settled on
 the ghc-proposals process as the official way to suggest user-facing
 changes to GHC.
