Outcome makes use of variable templates. There is still a code path
using types instead, but it is used exclusively on MSVC and I aim to
remove it as soon as Microsoft fix their compiler (I was told it'll be
VS2017 Update 1).

Outcome also makes heavy use of relaxed constexpr, but you're right it's
macroed out for VS2015. I intend to drop support for VS2015 before
Outcome enters Boost, if it is accepted, as VS2015 generates a lot of
code bloat when using Outcome which VS2017 does not. The MSVC specific
workarounds are also brittle and hacky, and I'd like them to go away and
use ISO C++ throughout.
