To merge two arrays in Perl, you can use the `union` function from the List::MoreUtils module or use the `push` method to concatenate arrays. Example: my @array1 = (1, 2, 3); my @array2 = (4, 5, 6); push(@array1, @array2);

Assuming both a local($var) and a my($var) exist, what's the difference between ${var} and ${"var"}?
