Hi, while searching for constexpr GUID from string generators, I found https://gist.github.com/AlexBAV/b58e92d7632bae5d6f5947be455f796f . Since I still work with VS 2015, I wrote a C++11 constexpr version incl. boost-uuid generators. If there's interest adding this to boost uuid, please have a look at https://github.com/tobias-loew/constexpr-GUID-cpp-11 NB. This is not a finished version to be added to uuid. Comments and BOOST-Macros for constexpr needs to be added. Tobias -- Sent from: http://boost.2283326.n4.nabble.com/Boost-Dev-f2600599.html
