Results class, what is it for?

I haven't understand this part. There is a loop and the val variable is replaced every time in the loop. Why is that?

@ mdbs99 Yeah, you're completely right. It's not the best way to do it. In this code we just want to execute all statements and get only the last result. We can do it using a for, but in this way it's cleaner ...
But I'll keep this issue open to think better on it. Any suggestion?

Any suggestion?

Concatenate all results before return the value.
