Discussion:
The current description of the associated state in 33.10.5 [futures.state]
does not allow for futures created by an async call. The description
therefore needs to be extended to cover that.
[
2010 Pittsburgh: Moved to NAD EditorialResolved. Rationale added below.

Rationale:
Solved by N3058.
Proposed resolution:
Add a new sentence to 33.10.5 [futures.state] p2:
2 This associated state consists of some state information and some (possibly not yet evaluated) result, which can be a (possibly
void) value or an exception. If the associated state was created by a call toasync(33.10.9 [futures.async]) then it may also contain a deferred function or an associatedthread.
Add an extra bullet to 33.10.5 [futures.state] p3:
The result of an associated state can be set by calling:
promise::set_value,promise::set_exception,or- packaged_task::operator()
., or- a call to
async(33.10.9 [futures.async]).
