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 :)

To that I say: let f = drop 1 . filter odd . take 30 in f xs -- :) -- Ben
