In ANSI CL, the defgeneric function takes a :generic-function-class option that should be 'the name of a class that can be the class of a generic function.' Similarly, the :method-class option should be 'the name of a class that is capable of being the class of a method.'

However, nowhere in the standard (AFAICT) is any standard way to create such classes specified. I get the feeling the metaobject protocol was amputated here, and these are some of the scars.

I've worked through about 2/3 of the CLOS section of the spec, just finishing writing tests for the builtin method combinations. After this section I think I'll write some tests of just when various def* forms have their effects during compilation and loading, since this seems to me to be a fertile area of bugs in CL implementations and programs.
