Extra stuff for union types
const Color = Type({RGB:[Number, Number, Number], CMYK:[Number, Number, Number, Number]});
const Color_ = Type({RGB:{Red: Number, Green: Number, Blue: Number}, CMYK:{Cyan: Number, Magenta: Number, Yellow: Number, Black:Number}});
const {Person} = Type({Person: {name: String, id: Number, leftEyeColor: Color_, rightEyeColor: Color}});
let person = Person({name: 'John', id: 1, leftEyeColor: Color.RGB(255,100,255), rightEyeColor: Color_.CMYK({Cyan: 50, Magenta: 80, Yellow: 10, Black: 25})});
let personWithoutEyes = Person('John', 2);
let person2 = personWithoutEyes(Color.RGB(100,100,100), Color.CMYK(30,30,30,0));
