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?

FWIW, the top Google hit for "boost future" links to the 1.55 docs (which do not have when_all), but there is indeed a big yellow box at the top of the page which links to the latest version.
Perhaps it didn't look enough like a hyperlink so you mentally skipped it. :)
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.
