Having a look at the forest with all those trees in the way...
Functionally, pop does 2 things:
1] removes the last element from an array and
2] returns that last element (for you to do things with)
Passing a literal array rather than a named variable means that the balance of the array is lost to the great bit-bucket in the sky immediately.
That means that the effect 1] above is lost.
That means that all you are really doing is 2] - getting the last entry in a list.
and that is very easily:
(Well, hard-coded like this, you may as well just grab the '9' and be done, but let's pretend this is auto-generated in an eval or something.)
