Oaklisp

    A portable object-oriented Scheme by K. Lang
   and Barak Perlmutter of Yale.  Oaklisp uses a superset of
   Scheme syntax.  It is based on generic operations rather
   than functions, and features anonymous classes, multiple
   inheritance, a strong error system, setters and locators
   for operations and a facility for dynamic binding.

   Version 1.2 includes an interface, bytecode compiler,
   run-time system and documentation.
