So there was this thread back in May about supporting case sensitivity 
in antlrV3.
Is there any support yet?
If not, has anyone managed to write a CaseInsensitiveLexer?
And barring that, is it actually just as simple as changing this one 
line in BaseRecognizer from this:
        if ( input.LA(1)==ttype ) {
...to this...
       if (Character.toUpperCase(input.LA(1)) == 
Character.toUpperCase(ttype)) {
