Comment (by ryanve):

 @toscho Priorities could work in one of two ways. I'm open to either.
 **1** is simpler. **2** is more capable:

 1. Subsequent (later priority) callbacks run as normal. `false` would work
 just like `__return_false` does now.
 1. Booleans provide a way to `break` from the loop. Subsequent (later
 priority) callbacks would not fire.
