 * This is the protocol by which a Parser makes callbacks
 * to the later phases of the compiler.
 * <p>
 * (As a backwards compatibility trick, Parser implements
 * this protocol, so that an instance of a Parser subclass
 * can handle its own actions.  The preferred way to use a
 * Parser, however, is to instantiate it directly with a
 * reference to your own ParserActions implementation.)
