- * A dynamic array is used to buffer up all the input tokens.  Normally,
- * "k" tokens are stored in the buffer.  More tokens may be stored during
- * guess mode (testing syntactic predicate), or when LT(i>k) is referenced.
- * Consumption of tokens is deferred.  In other words, reading the next
- * token is not done by conume(), but deferred until needed by LA or LT.
