--- Comment #2 from Nicholas Wilson <iamthewilsonator at hotmail.com> ---
Looks like something like
https://github.com/dlang/phobos/blob/master/std/complex.d#L656 would help here.

/*  Makes Complex!(Complex!T) fold to Complex!T.
    The rationale for this is that just like the real line is a
    subspace of the complex plane, the complex plane is a subspace
    of itself.  Example of usage:
    ---
    Complex!T addI(T)(T x)
    {
        return x + Complex!T(0.0, 1.0);
    }
    ---
    The above will work if T is both real and complex.
*/
template Complex(T)
if (is(T R == Complex!R))
{
    alias Complex = T;
}
