Silly question, but, can I test to see if any value of list a is

list b without doing a loop? A loop is easy enough, but wanted to

there was a cleaner way. By way of example:
List 1: a, b, c, d, e, f, g
List 2: z, y, x, w, v, u, b
Return true, since both lists contain b
List 1: a, b, c, d, e, f, g
List 2: z, y, x, w, v, u, t
Return false, since the lists have no mutual values
length(intersect(List_1, List_2)) > 0
