Re: [Caml-list] using infix operators/functions in modules when not using "open"

This is a local open (a more explicit notation is "let open Module in
foo op bar"). I think this is a fine solution: I don't like open, but
local mitigates its flaws.

Another solution is to rebind your operator locally:

  let (op) = Module.blah in
  "foo" op "bar"

(of course Module.blah doesn't need to be an infix itself)

If you are going to use an infix operator in a wide scope, I think
that such a rebinding solution is nice because it's more explicit,
which is good when it helps users understand the code.
