"If you dereference a reference and take a reference to the dereferenced reference, this reference will be the same as the original reference."

LOL :) It took me a lot of years coding Perl before I would have been able to understand exactly what's being said there. If one can grasp that, along with the actual syntax to do it, one can do anything.

It was my bad originally to claim they both work for different reasons. *That* was kind of a typo as well. I was thinking too far ahead at the time ;)
