in reply to help with references

Both times that the loop is run, \@a returns a reference to the same array, because it is the same array that's on the right of the \ character.

To avoid that, you can use $h{$i} = [@a] instead, which copies the array and returns a reference to the copy.

    Thanks for the reply, moritz! using your method i'm no longer getting a ref of @a, but now i get refs of the individual arrays instead. it still won't work because if i change the AoA in $h{"1"}, the AoA in $h{"2"} will also be modified.
    { '1' => [ [ 'a1', 1, 1, 1 ], [ 'a2', 2, 2, 2 ] ], '2' => [ $VAR1->{'1'}[0], $VAR1->{'1'}[1] ] }
