For those interested in giving it a whirl, the auto script converted "Boost edition" Outcome is now available at: https://github.com/ned14/boost-outcome Travis copies this into Boost and runs its test suite, so this Boostified edition is ready to go as a Boost library for a second review. There are no submodules in this converted edition, no external code at all, everything is Boost licensed. As per the last review feedback. What solely remains before it's ready for a second review is documentation. Anyone wishing to help out with writing the missing sections of https://ned14.github.io/outcome/ so it does not have unintelligible documentation like v1 Outcome did because I can't write tutorials anyone else can understand, please get in contact.
