   Hello,   
      
   I agree; another example is the keyword FORMAT in Fortran. No matter how   
   the scanner is implemented, generated or hand coded, the  FORMAT   
   statement requires forward scanning if the parser is deterministic,   
   in which case error messages can be IMHO descriptive, as shown ie here:

   Related examples with the lookahead operator '+:' can be found here:

   Hope, I'm not out of topic.
