This is probably a minority opinion, but I have written and read quite a lot
of OCaml code over the years, and I've seen surprisingly few effective uses
of the composition operator. Somehow, I usually find that code that avoids
it is simpler and easier to read.
I'm not averse to infix operators. At Jane Street we've found the following
sequencing operator to be highly useful:
let ( |! ) x f = f x
and it is indeed part of the default include in Jane Street's Core library.
