I didn’t give any examples with block function bodies, of course they are different from what I expressed. You changed the semantics and claim wrongness :/

Your words:

> One might be tempted to use the thenable interface (don’t!):

The code that followed was fine and it had no race condition.

> Seems like it would work, but it actually only waits for the promises returned from item() and not the .then() part!

This is the wrong part. The blockness is irrelevant.
