In fact, maybe all we need is a macro - if we don't already have it - C++ version. BOOST_CPP_VERSION.

What value would you set this macro to for a compiler which does not support the constexpr feature, but does support override and final? (Hint: this is a well-trodden path: http://thread.gmane.org/gmane.comp.lib.boost.devel/251820/focus=251967 ) Thanks, Steve.
