[Haskell-cafe] Composition and type magic

[Sumit Sahrawat, Maths & Computing, IIT (BHU)]

Hi everyone,

I defined a function for discrete convolution, i.e

    conv xs = sum . zipWith (*) xs . reverse

And I was wondering, can it be done without explicitly passing in the xs
(eta-reduction)?
I've seen people play with (.).(.) and foldl foldl foldl and was thinking
that maybe something similar might be used here.
