I have attached a little picture of how I imagined Brain's first
two statements. For those who can't deal with embedded GIF images,
I am sorry, but it is only 2KB so shouldn't be too much of a bother.

One thing that made it harder for me to follow Brian's explanations
is that I always imagine arrows going from the CDR to the CAR, and
not the way he did it. So the drawing helped me a lot - I made an
arrow start from and end in the middle of another arrow in order
to represent references. I didn't know who to represent "arrow is
part of a graph", so I used different colors for that.

You can see that my lack of comments is just pure ignorance (and
a lack of time to fix that).

BTW, I now have Squeak 2.6 running in my system (almost - I can't
make the network name resolutions system work so I have to access
everything by its IP address) so it would be interesting for me
to try the Arrows prototype. Where is it? I couldn't find it from
the Tunes home page...
