This would imply that the result of the fetch hook is ignored if the

This is the same for all the loader hooks, in fact.
Sounds good. Is there way, within a fetch hook, to conditionally
We have started investigating the implementation of generators in V8,
and a couple of questions popped up that are not quite clear from the

simply _delivering_ a sentinel object as end-of-iteration marker

One more thing worth pointing out is that a singleton does not work
