The point is that .then()/.catch() callbacks may return either a compatible Promise or a value of any type, *with one exception* - an object with a .then() method. A work-around was proposed, but it doesn't work with the current spec. Even AP2 wouldn't help in the general case. I think the spec should explicitly state that addressing the exception is out of scope for Promises. SeanReceived on Wednesday, 19 June 2013 05:32:15 UTC
