Hash keys and values are scalars not arrays, although you can store a
reference to an array in a scalar:
while ( my ( $name, $items ) = each %all ) {
> my $len = @items;
And then dereference the array:
my $len = @$items;

And dereference the elements:
# print "$name: $items->[0] $items->[1] $items->[2]
$items->[3]\n";
Or use an array slice:
# print "$name: @$items[0..3]\n";
