\ x y -> f (g x) (h y) [...] f $. g ~> h ~> id
I keep help wonder: other than a "5 chars", what is it we have gained?
Certainly in such a simple case, there's no benefit. In more complex cases, especially where we're focused on just writing the combinator itself (i.e., in cases where we won't use ($.)), I think it might make sense (there is an example in the comments of Conal's recent post at [1]). But anyway I do mean "might"... I happily admit the possibility that this may be nothing more than a curiosity. I'm happy to have found a solution to my little puzzle, but I'm not sure how often I'll actually use it. Time will tell, I suppose. Matt
