I must say that Brent Yorheys comment about (<**>) not being flip (<*>) has made the 'symmetry' argument less convincing and has moved me a bit closer to the - camp. However, I'm still for adding it because it can make code nicer.
They -- <**> and <$$> -- are symmetric in spirit. In the case of <$> and <$$>, the order in which things are evaluated doesn't matter. So we may say that <*>, <$>, <**> and <$$> are "always read from left to right" if we want to. Well, at least that's how I think ;). I too would like to see more people reporting their thoughts on this issue. Cheers, -- Felipe.
