Create an infinite generator that returns objects that fulfill the inexact? and complex? predicates. The real and imaginary parts of the complex numbers must be inexact. The generator should return the sequence

    0.0 -0.0 0.5 -0.5 1.0 -1.0
    0.0+1.0i 0.0-1.0i -0.0+1.0i -0.0-1.0i
    0.5+0.5i 0.5-0.5i -0.5+0.5i -0.5-0.5i
    1.0+1.0i 1.0-1.0i -1.0+1.0i -1.0-1.0i
    +inf.0+inf.0i +inf.0-inf.0i -inf.0+inf.0i -inf.0-inf.0i
    +nan.0+nan.0i
    +inf.0 -inf.0 +nan.0

first, then a uniformly random distribution of inexact complex numbers. Elements of the above sequence may be omitted if they are not distinguished in the implementation.

    (define inexact-complex-gen (inexact-complex-generator))

    (inexact-complex-gen) ; => 0.0+0.0i
