Easiest of all is to expose the compiler's internal state via a magic
namespace in the form of pseudo-template definitions. Then one has, at
metaprogramming stage, access to everything the compiler knows at that
I posited that idea to Chandler Carruth for clang at C++ Now. He didn't seem
Third party libraries (e.g. a Boost one) could wrap up each compiler's
internal magic namespace into something portable and therefore useful.
