Aside from fixing the comments... I think this needs more tests on corner cases. For example, what happens when you do

foreach a, b, c in array(array(1,2),array(3,4)) ?

Or the opposite case of

foreach a,b in array(array(1,2,3))

Also, what about:

foreach a,b in '{{{1,2},{3,4}},{{5,6},{7,8}}}'::int[] ?
