code dup. lets make a PromiseMirror:

var mirror = new PromiseMirror(value);
// use mirror.status();
// use mirror.promiseValue();

Done.

maybe [[PromiseStatus]], [[PromiseValue]] ?
what will you show in [[PromiseValue]] for a pending promise?

[Alexandra Mikhaylova, 2014/05/08 15:20:58]

Done.
For a pending promise, [[PromiseValue]] will be undefined.
