This shows a difference between the deprecated built-in complex numbers and std.complex:


void main() {
    import std.complex: complex;
    const cdouble cd;
    pragma(msg, typeof(cd.re));
    const acc = complex(1, 2);
    pragma(msg, typeof(acc.re));
}

It prints:

double
const(double)

Is such difference important and worth fixing?
It has caused a small problem when I have ported some code from cdouble to Complex, that contained typeof(data[0].re)  where data was a cdouble[].
