Need to diff() 2 arrays, anyone used Array::Diff? Docs say it returns
added and delted arrays but the example given shows a scalar.
my @old = ( 'a', 'b', 'c' );
my @new = ( 'b', 'c', 'd' );
my $diff = Array::Diff->diff( \@old, \@new );
$diff->count # 2
$diff->added # [ 'd' ];
$diff->deleted # [ 'a' ];
So, would the added be @added = $diff::added? Am I missing something
In my usage here, @old has 480 elements, @new has 489.
