  foo: {},
  bar: {},
};

cycled.foo.bar = cycled.foo;
cycled.bar.foo = cycled.bar;

var result = JSON.stringify(cycled, decycle());
// result === '{"foo":{"bar":{"foo":{"$ref":"#/foo"}}},"bar":{"$ref":"#/foo/bar"}}'

JSON.parse(result, retrocycle());
// => {foo: {{foo: [cyclic reference], bar: [cyclic reference]}}, bar: {{foo: [cyclic reference], bar: [cyclic reference]}}}
