I did *not* *remove* anything, simply, for C++11, real() and imag() are exactly
*per the letter* of the Standard, that is (similarly for the specializations):

      constexpr _Tp 
      real() const { return _M_real; }

      constexpr _Tp 
      imag() const { return _M_imag; }

and I don't see why we should do something different. But, if Gaby thinks,
everything considered, that we want something different, I'm not going to
object to patches to that effect (from a technical point of view, note the
functions are now constexpr, thus you can't simply have two overloads anymore)
