So Outcome requires C++14 then? Does this mean that compilation with
gcc 4.9.x is not supported?

Although I have not yet attempted my own implementation of
expected/outcome, it seems to me that an implementation using only
C++11, or even only pre-C++11, is quite possible. There are still many
shops that are "stuck" on particular older versions of Visual Studio.
Restricting a generally useful library which parallels a standard
library proposal, to only the latest version of Visual Studio sounds
quite harsh.

Thanks
