Comment(by mevenson):

 I envision this as resulting in a Java class that has specialized
 constructors/static initializers that somehow "connect" a given Lisp
 implementation (hashtable of constructors, variables, and methods?) to a
 running instance of Interpreter.

 Some questions towards an implementation:

 1.  Syntactically how would one specify access to member variables in the
 superclass?

 2.  The Lisp implementation would probably have to be marked as final, as
 enabling the extension of the Lisp version again in Java would be too
 tough?

 3.  Would one have to run static initializers in the super class(es)?

 The more I think about it, this would be a non-trivial amount of work, as
 it basically means re-inventing much of the mechanisms of Java (the
 language) in Lisp.
