take on #775
Adding test case for #775: runtime error with local dataflow (copying futures?), making dataflow compile with MSVC
Keeping dataflow frame alive during actual function invocation (saves copying the tuple of futures)
Adding test case for #774: using local dataflow without explicit namespace
Adding test case for #773: local dataflow with unwrap: functor operators need to be const
Adding missing typename
Removing duplicate test
Fixing #775: compiler chokes on dataflow overload with launch policy
