Given an mpl::vector of keys, and a fusion::vector of values, what's the
easiest way to create a fusion::map?

The obvious solution of just zipping the two sequences and passing the
result to fusion::as_map doesn't work because as_map (somewhat narrowly)
requires all elements to be fusion::pair, and Fusion's zip algorithm
produces sequences of vector2. I'd like to see this generalized so that
(a) as_map only requires sequences of 2-tuples and (b) fusion::pair
meets the requirements for 2-tuples.
