I can't see a use for arrays unless they support multi-dimension. If not, then hash tables can do the same things, essentially.
/hmake array
/hadd array [1] blah
$hget(array,0).item
(not sure what the .append would do)
/hfree array
If arrays were added, a FOREACH structure should be added with it, as it would permit simpler loops with arrays.
