I am not sure I follow.  This works fine (not that I recommend it):

#!perl -wl
@array = (0..9, [0..9, [10..19, [20..30]]]);

# on-the-fly
print $array
 [$#array]
 [$#{$array[$#array]}]
 [$#{$array[$#array][$#{$array[$#array]}]}]
 [$#{$array[$#array][$#{$array[$#array]}]
   [$#{$array[$#array][$#{$array[$#array]}]}]}];

# making reference to each subarray first
$level{0} = \@array;
$level{1} = $level{0}[$#{$level{0}}];
$level{2} = $level{1}[$#{$level{1}}];
$level{3} = $level{2}[$#{$level{2}}];
print $array
  [$#{$level{0}}]
  [$#{$level{1}}]
  [$#{$level{2}}]
  [$#{$level{3}}];

# i know what i want!
print $array[10][10][10][10];

All of these access the same variable.
