[antlr-interest] Resolving conflict between keyword and identifier

In my lexer I use:
testLiterals = true;
and then for the keyword rule I have a list of token types rather than a
list of string literals.
Works for me, with many hundreds of keywords. (Of course, make the keywords
list big enough and you can run into the old "virtual memory exhausted"
error from G++, but that's another issue)
