Neither. In the above, Crafty is playing against the toolkit, not Symbolic's
Lisp engine. It does show that the toolkit's primitives, used by the Lisp
engine, can by themselves put up a decent fight. Mostly it shows that the
CTXboard class works without crashing or hanging.
There is still more work to be done with the toolkit, and much more work to be
done in Symbolic's Lisp domain. So overall, Crafty doesn't have much reason to
fear Symbolic. For now.
