I don't completely understand this whole lazy evaluation, so I'm confused
how these functions would work on them.  Explain to me how you would zip
and unzip/partition sparse lists.  For example, let's say I have list like:

$A[0] = 1, $A[2] = 5, $A[3] = 7, $A[5] = 11
$B[1] = 4, $B[2] = 6, $B[4] = 10, $B[5] = 12

How would these operators work on them?
