Great stuff! Truly is a massive improvement to an already venerable API.

Was there any consideration to make this a new module ‘Dispatch’, and drop all the Dispatch- prefixes? Or rather, what is the reason for keeping the prefixes? (Group could become WorkGroup to lessen naming conflicts)

Much of the discussion has centered around specific details in the proposal - for example the “.asynchronously” method on DispatchQueue.  This great discussion leads to several requested revisions in the proposal:
> - Rename the DispatchQueue.[a]synchronously methods to ".async” and ".sync”, to follow the term of art.
> - Rename DispatchIO setHighWater, setLowWater --> setLimit(highWater:), setLimit(lowWater:)
> - Rename setTargetQueue(queue:) and DispatchSource.setTimer 
> - Rename Semaphore, Group and WorkItem: .wait(timeout:) --> wait() and wait(withTimeout:)
> - Expand source handler methods to take the same arguments as async()
> - Expand DispatchQueue.after to take the same arguments as async() in addition to the when: argument
> Thank you to Matt Wright proposing this, and for all of the implementation work that has gone into this so far!
