(.) 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 :)
