This Nu code defines a simple complex numbers class. (class Complex is NSObject (ivar (double) real (double) imaginary) (- initWithReal:(double) x imaginary:(double) y is (super init) (set @real x) (set @imaginary y) self)) The example is a basic definition of a complex number: it defines the instance variables, and a method to initialize the object. It shows the similarity between the code in Nu and the equivalent in
