I'm an end user of Haskell rather than an FP researcher, and I'm very strongly against this change because I don't think of $ as being function application; I think of it as the "brackets from here to the end of the expression" operator. I've always assumed that it was defined with the associativity it currently has in order to support that use. As it stands, it's one of my favourite features of Haskell. I find it particularly useful when constructing nested data structures; at the moment, it's very easy to write something like: Seq m $ Spec m var $ Only $ ProcCall m name args In that case, $ clearly has the same meaning each time. If I put something like that on a slide, I can explain the meaning of $ in a few seconds, even to an audience who aren't familiar with functional programming or Haskell. Forcing me to change the first two to . would make the code harder to write, harder to understand, and harder to explain. If people want a left-associative application operator, then it ought to be a new operator; please don't change the existing one. -- Adam Sampson <[EMAIL PROTECTED]> <http://offog.org/> _______________________________________________ Haskell-prime mailing list Haskell-prime@haskell.org http://www.haskell.org/mailman/listinfo/haskell-prime
