Hi! all,
I was wondering if the following is the best way to grep non-equal elements from two arrays. 

for my $item (@all_genes) {
   say  "$item" if ! grep {$item eq $_} @covered_genes;
}

Should I expect my code to work properly (it's working fine in my tests). If I wanted to use "ne" operator, how could I write the code. I would appreciate suggestions. Thank you.
