20   * Wrapper class for `compound' operations, virtual instructions that
21   * don't exist as byte code, but give a useful meaning. For example,
22   * the (virtual) PUSH instruction takes an arbitray argument and produces the
23   * appropiate code at dump time (ICONST, LDC, BIPUSH, ...). Also you can use the
24   * SWITCH instruction as a useful template for either LOOKUPSWITCH or
25   * TABLESWITCH.
26   *
27   * The interface provides the possibilty for the user to write
28   * `templates' or `macros' for such reuseable code patterns.
