This is pretty neat.  Yes there is no reason that CLOS or at least very
usefull form of a object system that reuses existing java class should not
be defined by macros to make it smooth

I used to imagine that the runtime-class.lisp was piso's original
plan (generated java classes from lisp .. which these objects could be
mixins subclasing pre-exisitng java classes)
In my ABCL Clojure extension
(this file is simplistic becasue some code is i the non-lisp sources) but
you get the gist.

I preroll existing C#/.NET class into a set of existing methods gleaned from
java's reflection using a name-mangling contract (as-needed).
In cases I have multple possible methods per class (or interface).. i end up
doing a (defun someclass-somemethod (self &rest args) (... guess the right
jcall ....))

Static class  fields, like   String.CASE_INSENSITIVE_ORDER i make a symbol

But my blindspot still is on how to please a more CLOSy clonsuming codebase
so I am very interested in seeing how you set things up from your macros.
