As an aside, I would have liked (some pred coll) to return the item
that makes the pred true and the current implementation of `some to be
renamed `any? so that we would have the following:
(any? odd? [2 4 5 12]) ;; result is true
(every? odd? [3 5 6 13]) ;; result is false
(not-any? odd? [2 4 5 12]) ;; result is false
(not-every? odd? [3 5 6 13]) ;; result is true
(some odd? [2 4 5 12]) ;; result is 5
Mathematically, for the first four,
(Ex in [2 4 5 12])(x is odd)
(Ax in [3 5 6 13])(x is odd)
~(Ex in [2 4 5 12])(x is odd)
~(Ax in [3 5 6 13])(x is odd)
