<div>Thanks, but the most important thing you can try to do with this

<div>What's supposed to happen is that all the arrows for 1, 2, and 3
are supposed to be created and linked together over monoid's arrows
appropriately, so that you can do simple counting up and down. I'll
write this up for the next release.</div>

<div>Hell, those were just the demo tests. I have a much larger set of
things it's supposed to do and is nowhere near ready to accomplish ;)
Just look at all the non-functional code in the SmalltalkMOP category.
And of course there's the infamous equational semantics.</div>
