--- Comment #1 from Howard Hinnant <hhinnant at apple.com> ---
This looks like a very good direction to me.  However the addition of constexpr
to functions and member functions is a non-conforming extension.  Even the
C++1y-conforming constexpr additions we are wrapping in macros to ensure that
they are not turned on when C++11 is asked for.  The addition of constexpr can,
amazingly, cause runtime errors.

The way to make this happen is to write a paper for the C++ committee:

http://www.open-std.org/jtc1/sc22/wg21/

Anyone can participate in the C++ standardization process, and many do.  It is
a lot of work.  You don't get everything you ask for.  It takes a long time. 
And many find the work rewarding.
