        language based on {Hybrid Group Architecture}. ABCL/R2 was
        produced by ,

        , at the {Tokyo Institute of
        Technology} in 1992.
     
        As a reflective language, an ABCL/R2 program can dynamically
        control its own behaviour, such as {scheduling} policy, from
        within a user-program.  This system has almost all functions
        of {ABCL/1} and is written in {Common Lisp}.
