using PG'OCaml with Async

[Ashish Agarwal]

Does anyone have an Async implementation of PG'OCaml's functor argument [1]. I tried:

type in_channel = Reader.t

type out_channel = Writer.t

but then I need

val open_connection : Unix.sockaddr -> (Reader.t * Writer.t) Deferred.t

which I can't find in Async. The Socket API [2] is quite different from Stdlib and Lwt, and I don't know how to map it to what PG'OCaml wants.

I've never used Async, so I won't be able to help you directly.  I do however have
a somewhat related question: is PG'OCaml's reliance on Batteries a big turn-off for
users of Async/Core?  I imagine it might, which is why I'm considering dropping the
Batteries dependency.  It turns out there's only a couple of Batteries functions we
actually use, so it might be worth just copy + pasting them into PG'OCaml if that
means one fewer big dependency. (Yes, code duplication is evil, but so is scaring
away a huge chunk of potential users...)

Best regards,

I'm not as sensitive to extra dependencies as others, so I personally don't care. However, if it is really just a few functions, I suppose the dependency should be removed.
