In order to test out the "operator type" facility in Draco V1.2, I implemented
a complex number type. A friend here, Don Reble, did some of the complex
trancendental functions for me. With it, you can do things like

    complex a, b;
    
    readln(a, b);
    a := a * b;
    writeln("a = ", a, "b * 3 = ", b * complex(3.0, 0.0));
    etc.

This new version should be out this month (probably on Compu$erve as well
as sending it to Fred Fish) - there is only one thing left on my list of
"things to do before release". The full source for the complex number
package will be included.
