It's sure to create arrays. Those ones that hold the corresponding
values from the original arrays, and only for the duration of the
current iteration. But if you zip two 100-element arrays, it won't
duplicate either simultaneously, it'll just create two-element arrays to
be passed to the block temporarily.

Is that so bad?
