I like chain too, and the V8 implementation in general.  However, note that
the V8 implementation does not comply with the current spec.  According to
the current spec, the *output* side of `then` is recursively unwrapped.
 This is, of course, incompatible with the AP2 design principle that the
consumer determines the unwrapping strategy, and not the provider.
