I'm not clear what kind of "combine" you had in mind.

   * If you meant to use them together, I think that's fine. They
are both user level libraries, Lwt has an asynchronous interface,
camlish has a synchronous one, so you can just use camlish API as
common functions application everywhere.

  * If you meant to implement the inside asynchronous mechanics of
camlish on top of Lwt, I did thought of that. Actually, I have
another library called Async does similar thing as Lwt. It's
possible, but not necessary. Besides, the CPS-based approach
always brings some syntactic burdens, which I prefer to avoid.
So finally, the inside implementation of camlish is asynchronous,
while we only expose the synchronous interface to the outside world.

  * Maybe you were though about parallel execution? Pipeline is
parallel already, plus there are two parallel combinators have
been planed (opposite to "&&&", the sequential combinator). I
haven't seen this kind of stuff in other shells, but I think that's
reasonable.

HTH.
