But beyond that I am kind of at a loss. I use them alot (like you say) to push on array onto another without clobbering the first one. I also create anon refs to arrays to pass to subroutines if they are large arrays, instead of passing the entire large array by value to a sub. You will see alot of useful things for them when you get to the data structures part of the book.
