/*
 * Used to dump enums in forth mode.
 *
 * Enums are simple - there is no member-specific mode for them.  We get
 * the header op at the start, and we save the type id for dumping later.
 * If we get the members op, we've been invoked in member-specific mode,
 * which is a syntax error for an enum.  When we ge the trailer op, we
 * dump all of the members and the trailer thus concluding the enum.
