Really? The only real() that I can see is const, and anyway, how would
we implement that? std::real() and std::imag() only return references
with certain GCC implementations while e.g. on GCC 4.0 / Mac they
return by value.

It seemed to me that allowing that was one of the things that would
require us to have our own complex numbers class.
