I had my first Ruby epiphany when I was working on a netlisting
tool where I needed to be able to traverse the hierarchy in
both directions.  When I wrote the following line of code in the
"add a new block to the hierarchy" method:

  child.parent = self

the profound, fundamental truth of that statement -- as bad of a
programmer that I might be -- let me know that I was doing something
right.  :^)

Cheers,
