No. Per the definition of the then() method and
http://dom.spec.whatwg.org/#concept-future-wrapper-callback then()
will just be invoked with the result of the future. Future.accept()
sets the result of the new future to the argument it was passed.
Future.resolve() sets the result of the future to the resolved value
(does unwrapping of a thenable).
