The array pointer can be pretty useful. ie. give me the second last
element of an array:
end($arr);
echo prev($arr);
Or have it tell you what the index is at the second last element:
end($arr);
prev($arr);
echo key($arr);
and the index before that one:
prev($arr);
echo key($arr);
Perl has these too, they just aren't user accessible.
