   The grammar itself as defined in the original note is trivially LL(1)   
   after the left recursion is removed. A quick yacc check would probably   
   say it is LALR(1) as well. Another reason that scanners and parsers   
   are kept separate is that the more powerful pushdown automata is not   
   needed for scanning. If you use a sledge hammer to crack a walnut, do   
   not be too surprised if you end up with squashed nut meat.
