Since hashtable item names can be pretty well anything, i dont see any problem with just using them, I wouldnt see any problem with having arrays either, just i doubt that khaled wants to add features already implemented in other forms.
array[34,24,56]
$hget(array,34-24-56)
and if u didnt like that use
$array(34,24,56)
alias array { return $hget(array,$+($1,-,$2,-,$3)) }
