How about just array_pos() if any. The remaining functions can easily
be implemented in userland like:
function array_pos_isfirst(Array &$array) {
return array_pos($array) == 0;
}
function array_pos_islast(Array &$array) {
return array_pos($array) == (sizeof($array) - 1);
}
I don't think it should be needed to add array_pos_isvalid(), since it
*shouldn't* be possible to point to an invalid position. Rather
"isset($array['key'])" should be used to check if a position is valid.
