A result of the pop function.

Variants

`Data`	Some data has been popped
`Empty`	The queue is empty
`Inconsistent`	The queue is in an inconsistent state. Popping data should succeed, but some pushers have yet to make enough progress in order allow a pop to succeed. It is recommended that a pop() occur "in the near future" in order to see if the sender has made progress or not
