- vector-every pred? vec_1 vec_2 ···procedure
If, for every index i between 0 and the length of the shortest vector argument, the set of elements (vector-ref vec_1 i) (vector-ref vec_2 i) ··· satisfies pred?, vector-every returns the value that pred? returned for the last set of elements, at the last index of the shortest vector. The iteration is strictly left-to-right.
