[antlr-interest] Profiler of ANTLR usage

[Martin Probst]

Hi Ruslan,

the last time you said you wanted to investigate some possible changes
to the ANTLR runtime. Did you make any progress on that? I think I
remember you wanted to remove the std::string part, did you manage to?
I'd be curious. Do you use semantic predicates "( ... ) =>" btw?

Martin
