I didn't realize that existed.  It's not so bad -- it lets me have my
cake and Jon eat it, too.  :D

I often use the poor man's local operator overloading already built into
the core OCaml:

let result =
    let (+) = Vector.add and ( * ) (x:int) (v:Vector.t) =
Vector.scalarmul x v
    in 3 * a + 2 * b

This makes overloading local and explicit, and at the same time makes
expressions clear. I do not miss implicit overloading.
