Special-casing for complex sounds ugly to me; "complex float"
is a type name in the same way as "long int" is, and writing
"real_t complex" feels a bit like writing "int_t long".
But of course, if this feature is really only needed for declaring
complex variants of real types, then how it is done doesn't matter
so much. But, IMHO, such a special casing would be a somewhat weird
