I'm trying to wrap Python's PyComplex type. It stores the real and imaginary parts as two doubles. D, of course, has complex numbers built-in. I would like to provide a member function like, e.g.:

cdouble asComplex();

Which would take the two parts and combine them into a D cdouble. However, I can't seem to convert the two doubles into a cdouble. The .re and .im properties are read-only, and the following doesn't work:

cdouble c;
double a = 2.4, b = 3.8;
c = a + cast(idouble)b;
// c now equals 2.4 + 0i

What am I missing?

c = a + b * 1i;

Ahhhh, of course. Thanks!
