So the advantage of dot from that point of view is: * dot already appears tightly-bound in qualified names * dot is already a reserved operator, so we won't have to search for some other candidate
(.) is not a reserved op, it is defined and redefinable like every other operator and has no special fixity rules. main = do let x . y = x + y print (3 . 8) prints 11 like you would expect. Oddly enough, I have occasionally wanted (.) to bind tighter than function application but still be composition. map toUpper.chr xs has a nice feel to me :) John
