I'm sorry, I take it back. Things were fine until I included <boost/hana.hpp> I had been testing with <boost/hana/core/when.hpp> and the likes of: template<class T> constexpr T pi = T(3.1415926535897932385); // variable template which would not work until I patched.
And to quote: In this release, we've updated the C++ compiler and standard library with enhanced support for C++11 and C++14 features, as well as preliminary support for certain features expected to be in the C++17 standard. The most notable compiler changes include complete support for generalized constexpr.
Maybe next time....
Best, Dan.
Variable templates have been supported for a while. I know I have been using them in the compiler source code itself for a long time now. If you find a bug with respect to variable template support, please do let the VC++ team know about it.
