I think a joint review is a very good idea. I think there should only be one
boost.futures library, and both our libraries offer slightly different
perspectives, so they should be discussed together and the "best" interface
chosen, which may be entirely new, but likely contains elements from each.

Totally agreed. The proposal hasn't been approved by the committee yet, and
part of my drive in implementing it is to get feedback before it is approved
by the committee. We want to standardize the best interface we can get in the
time available.
