I don't get why the name isn't "arrow" instead of "arr"... Arr reminds me of pirates, "arrrrrrrhh" ;-) I guess "first" was chosen because "fst" was already taken, but then it would be logical to choose "arrow" instead of "arr" ;-) Ross Paterson wrote:

Perhaps not. I used the name pure for arr in the Fun of Programming paper, because Richard Bird preferred that name, but it hasn't caught on, and now the same name is used in the Applicative class. So perhaps it should be removed from Arrow. _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
