Comment (by simonpj):

 > My understanding is that INLINEABLE will merely tell GHC to produce an
 unfolding; it won't ensure that GHC will use that unfolding to specialise
 use-sites.

 Actually it ''does'' tell GHC to do exactly that.   In other words, it
 already seeks to meet the goal.  It may or not be working, of course.

 I did try #8774 with HEAD and it worked flawlessly.
