Arrays in perl are always one dimensional. You have an array which
contains references to arrays.</pedant>
If you want to get out a lower level array, you just use @{} to
dereference the apropriate arrayref.
@foo = @{ $bar->[23]->[42] };
Keep in mind that this makes a copy of the contents of the array
referenced by what's in $bar->[23]->[42] and modifying (say) $foo[0]
will not do anything to $bar->[23]->[42]->[0] (to do that you'd want
to instead do: $foo = $bar->[23]->[42]; $foo->[0] += 17).
See perldoc perlreftut, perldoc perllol, and perldoc perldsc.
