  this.weight = weight;

var randomAnimal = qc.constructor(Animal, qc.pick('tiger', 'cow'), qc.natural);
class Animal
  constructor: (@type, @weight) ->
randomAnimal = qc.constructor Animal, qc.pick('tiger', 'cow'), qc.natural
class Animal {
  constructor(public type: string, public weight: number) {}

let randomAnimal: Animal = qc.constructor(Animal, qc.pick('tiger', 'cow'), qc.natural);
