We already have a sort of metaclass to represent Java classes and do
CLOS dispatch on them.

You cannot instantiate it, and you cannot use it as the metaclass of
user-defined classes.

Having (make-instance (find-class "com.xxx.MyClass")) work is not that
hard imho (and probably Erik's implementation of metaclass support in
our CLOS will help).

Having user-defined classes use java-class as the metaclass is harder.
CLOS has a number of things (like change-class and class redefinition)
which aren't easy to map to Java classes. Given that we want to have
runtime Java class generation (or do we have it already?), it'll
probably be easier to just provide a tiny layer on top of that to dump
the byte[] to a .class file.
