If $val2 is a regular scalar, then ref($val2) will return undef since it is not blessed. Makes perfect sense, right?

I'm not sure why you have a ref call in there.

You might also have made a mistake in your first loop. $val declared in your loop, $val2 used in your print. You should have got a warning.
