/**
 * This is not a node in the classic sense in that it has no defined or
 * interpret method which can be called.  It just stores the position of
 * the literal and the name/value of the literal.  We made it a node so that
 * the parser needs to work less hard in its productions.  dynamic literals
 * are nodes and by having literals also be nodes means they have a common
 * subtype which is not Object.
