Comment (by dd32):

 > it does however, return false when $priority is set to an array or
 object. I added that because I was getting an 'Illegal offset type' thrown
 in the console when I tried to assert they were false.

 This is the type of error that we'd normally leave in place, as a
 development warning to the developer that they're passing something in
 that  doesn't evaluate in a manner that works. That might sound counter
 intuitive given the concerns raised here, but as long as a warning isn't
 something that should be generated in the normal runtime and correct use
 of a function, we generally leave it there for the dev to pick up on.

 Realistically I agree with adding a unit test that covers it, but I do
 question if unit testing the addition of filters is worthwhile, and rather
 that a test on the order of execution might be more useful.
