I can't figure this one out.

I would appreciate any help anyone can give.

This snippet below has a scalar reference pointing to an array. The second member of the array is a reference pointing to another array.

The code in question is: 
$aray_size = scalar (@$states[ 1 ]);

After this line executes, my debugger says that $array_size is now an array, not a scalar holding the length of the array. Why??? 
my $states = [ ];            # Annonymous array constructed
push @$states, 'Oregon';
print "@$states [ 0 ]\n";

my $city;
my $cities = [ ];            # Inner annonymous array constructed 
push @$cities, "Portland";
push @$cities, "Salem";
push @$cities, "Bend";
push @$states, $cities;

my $counter;
my $array_size = scalar (@$states [ 1 ]);  # here

for ($counter = 0; $counter < $array_size; $counter++) {
print "\t@$states [  1 ]->\[$counter\]\n";
}
