Should BOOST_STATIC_CONSTANT be changed to add the C++11 "constexpr" attribute, if it's defined? I guess we would need a preprocessor flag to check if constexpr is available.

We have a config macro for that, but I don't see what constexp can add in this case?

Clearer / earlier compile errors when the expression is not really constant? Doing the right thing with UDTs, whilst still supporting integer types on legacy compilers? John Bytheway
