        System.out.println("Testing == " + some.getOrElse(easy));

        System.out.println("Tricky == " + none.getOrElse(easy));
        
        System.out.println("Some length == " + some.map(length));

output

Testing == testing
Tricky == This is much less tricky than I expected
Some length == Some(7)
None length == None
