Comment (by simonpj):

 Thanks for doing this!

 But before I can review this I need a specification of what the change is,
 exactly.   It's hard to review code without knowing exactly what it is
 trying to achieve.

 In fact, it should really be a GHC proposal -- it's clearly a user-facing
 change.  It'd be an easy proposal to write, and could be reviewed quickly.
