      Guaraná is a reflective architecture that aims at simplicity,
      flexibility, security and reuse of meta-level code.  It is implemented
      as an extension of Kaffe OpenVM$^{\rm (TM)}$, a free implementation of the
      Java$^{\rm (TM)}$ Virtual Machine.
    \par
      We describe the Java classes that implement the meta-object
      protocol of Guaraná, and the modifications introduced in the virtual
      machine to intercept and reify of operations.
      Finally, we evaluate the performance impact of our modifications,
      and suggest some optimizations that may be implemented in the future.
