    019/**
    020 * Wrapper class for 'compound' operations, virtual instructions that don't exist as byte code, but give a useful
    021 * meaning. For example, the (virtual) PUSH instruction takes an arbitrary argument and produces the appropriate code at
    022 * dump time (ICONST, LDC, BIPUSH, ...). Also you can use the SWITCH instruction as a useful template for either
    023 * LOOKUPSWITCH or TABLESWITCH.
    024 *
    025 * The interface provides the possibility for the user to write 'templates' or 'macros' for such reusable code patterns.
