Hi,
If you just want a short notation for (fun x -> x |> f |> g |> ...),
why not simply define a composition operator?

With
let (->-) f g x =  x |> f |> g;;
you can rewrite the previous expression as f ->- g ->- h ...
I personally don't think that there is any need for a special syntax here.

At the same time, it could be nice if there was a standardized name for
composition operators.
