I think the cutest way to get what you want here is to define a new
operator as follows:
(.<) = (.) . (.)
(the choice of symbol is supposed to suggest this new form of
composition with "two prongs" on the right). Then you can use it as
follows, for example:
f x = x * x
g a b = a + b
Hi,
you may use (f .) . g.

Hi,
Hopefully this is a simple question. I am wanting to know good ways
of using ".", the function composition operator, when dealing with
currying functions.
Suppose I have the following functions defined:
f :: Int -> Int
f x = x*x
g :: Int -> Int -> Int
g a b = a + b
If I wish to ad
