According to http://www.cs.usfca.edu/~parrt/course/652/lectures/antlr-lexers.html
it ought to be possible to modify a token's text two ways:
FOO: '<'! ... ; // '<' does not become part of the token
FOO: '<' ...{ $setText (...); // $setText manually overrides the matched text.
Neither of these constructs seems to work for me...were they perhaps
taken out or changed to something else? I see there is a setText
method on Lexer, but can't make it work: does FOO: x=TOKEN {$x...};
notation actually work?
