--- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Also, C++11 requires constexpr for the standard specializations,
std::complex<float>, std::complex<double>, and std::complex<long double>. The
effect of instantiating the primary template is unspecified by the standard, so
we're allowed to make it constexpr.
