[antlr-interest] each keyword allowed as Identifier

Please search antlr.markmail.org for using keywords as identifiers and for the word 'poker' as there must now be about 50 people who have written ANTLR parsers for this! If someone would donate a parser to the ANTLR grammar list it would save a lot of people a lot of time, but I suggest it would not save most people money ;-)


id: ID | MIN | MAX | ...... etc ;

The use this instead of ID. I suspect though that these log files are easier to 'parse' in a manual fashion where you lex in context.
