Could you explain the rationale?
   Element queue::value_pop();
can be used with no default constructible types
while
   queue_op_status queue::pop(Element &);
not.
yes - you are right. I was more focused on a symmetry of the interface
(returning queue_op_status)
There's the question of what should happen to a caller blocked in
value_pop() when the producer calls close(). Returning queue_op_status
seems safer.
The proposal throws an exception.
