Or remove most of the restrictions on constexpr functions that were necessary
only to win approval for C++11.  This case doesn't strike me as one of
those where you fight complexity with even greater complexity.

Allow loops and the like in constexpr functions and be done with it.  See my
comments on the C++ Extension Working Group when these (and related)
issues where brought up.
