This raises a point about ongoing development of Clotho: I definitely 
think the way Randall Beer and Gary Byers are approaching the interface 
to Objective C is the desirable way to go (that is, making Objective C 
objects look like CLOS objects). Thus, as they progress with their work 
I'm going to want to change the way that Clotho works to use their new 
code. That's going to introduce soome thrash into the Clotho project, 
but I think in the end it'll be worth it.
