020/**
021 * Wrapper class for `compound' operations, virtual instructions that
022 * don't exist as byte code, but give a useful meaning. For example,
023 * the (virtual) PUSH instruction takes an arbitray argument and produces the
024 * appropiate code at dump time (ICONST, LDC, BIPUSH, ...). Also you can use the
025 * SWITCH instruction as a useful template for either LOOKUPSWITCH or
026 * TABLESWITCH.
027 *
028 * The interface provides the possibilty for the user to write
029 * `templates' or `macros' for such reuseable code patterns.
