Next problem :)

asio's use_future returns a std::future. when_all() expects boost::futures.
I can't find an obvious way to convert between the two and/or get
asio's use_future to return a boost::future.

My understanding is that std::futures are pretty much a re-namespaced
boost::future (aka, boost's implementation was standardised).

My compiler (clang, Apple LLVM version 8.0.0 (clang-800.0.42.1),
bundled with Xcode 8.2.1) doesn't come with experimental/future (see
http://en.cppreference.com/w/cpp/experimental/when_all)

Besides re-implementing all the "magic" in asio/impl/use_future.hpp,
is there a way to mix these future types?

Now that you've told me that its there I can't miss it. Perhaps I just
mentally skipped it before as it doesn't look much like a link and is
inline with the header.
