I just read the code now (yeah, it takes me a couple of months to do
things), and WOW. I didn't know the CL condition system could be
implemented so simply out of weaker primitives, and I didn't realize
that the CL condition system is actually as simple as it is! All the
CLHS and tutorial descriptions make it sound a lot more complicated.
Red, I like your implementation.
And just to state the apparent: dynamic scoping FTW.
