  /**
   * This interface contains shareable instruction objects.
   *
   * In order to save memory you can use some instructions multiply,
   * since they have an immutable state and are directly derived from
   * Instruction.  I.e. they have no instance fields that could be
   * changed. Since some of these instructions like ICONST_0 occur
   * very frequently this can save a lot of time and space. This
   * feature is an adaptation of the FlyWeight design pattern, we
   * just use an array instead of a factory.
   *
   * The Instructions can also accessed directly under their names, so
   * it's possible to write il.append(Instruction.ICONST_0);
