Comment (by sgraf):

 Replying to [comment:15 danilo2]:
 > I strongly disagree with the sentence that the "fix would be to remove
 INLINE pragma" because this leaves us in a world where GHC performance is
 completely unknown and we have to randomly enable / disable things hoping
 that it will magically get better. I suspect @sgraf that you didn't mean
 "fix" but instead a "dirty workaround for now", but I preferred to
 emphasize my worries regarding this matter.

 Yes, exactly. I'm not happy with doing this (or rather having to
 anticipate doing this), either.
