-1 Reasons have already been given in previous threads on this. However, I'd point especially to the fact that people don't *agree* that this is more readable as a very strong point against -- regardless of whether any one individual thinks it's more readable or not. The point is the there seems to be a lot of disagreement -- that indicates to me that this cannot by definition be a "clear win"[1]. Disclosure: I personally find it less readable because of the implicitness. Implicitness which has a non-trivial probability of affecting semantics is bad in my book. Frankly, if it came to it, I'd rather just remove $ and deal with the parentheses. Regards, [1] Which I should think the barrier to extensions should roughly be :). _______________________________________________ Glasgow-haskell-users mailing list Glasgow-haskell-users@haskell.org http://mail.haskell.org/cgi-bin/mailman/listinfo/glasgow-haskell-users
