[ocaml-platform] Changes to my previous proposal for namespaces

[Yaron Minsky]

It occurs to me I just don't understand the semantics of this.  What
happens if I do this:

    open namespace Core
    let () = printf "Hello world!\n"
    open namespace Async
    let () = printf "Hello world!\n"

or, for that matter:

    open namespace Core
    let () = printf "Hello world!\n"
    let open namespace Async in
    printf "Hello world!\n"

Async and Core have different definitions of printf, as it happens.
Which gets called in these cases?
