Interesting. But why does this need Then instead of plain chaining? This
is an
honest question. For example, I don't understand why you would need
thenable
assimilation on the API side.
ScriptPromise::then will be used by Blink developers to attach handlers to a
Promise provided by a JavaScript developer.
If we don't have |then|, we have to specify to pass a Promise that wraps an
object exactly once to DOM methods, i.e. a JavaScript developer should know
if
it is a Promise of an object or a Promise of a Promise of an object. It is
nonsense I think. We need recursive unwrapping.
