heh heh, that whole approach is terrible. I must have been thinking that
eval has magical access to a macro's lexical environment.
The best we can do seems to be to generate the class, and if its not already
defined (presumably from AOT), either defineClass or writeClassFile based on
*compile-files*. I don't think its possible to error out on an already
defined class unless we can figure out that we're not in the initializer of
an AOT compiled module.
