Thanks for those insights. I just discovered a relevant discussion on what I was trying to understand - a reference to an array of arrays.

I have discovered that the documentation in the "perllol manpage" is pretty good for this subject.

Also, I consider the syntax of $ArrayRef->[$index] to meet my "Elegance" standards (Better than $$ArrayRef[$index]). The glob stuff seems cool too, but, without a full understanding of the implications, I'll treat it as dangerous and eschewable.

Thanks for bestowing all the wisdom, and cleaning up my message format. (I'm still learning, and hope to do that for the rest of my life).
