Hi


I've already started developing this project using flex and bison, and
reached a good stable point.


The problem was actually that I had also to recognize things such as
class and method definitions apart from new constructs.


Indeed I had some problems in reading all the rest of code as it is and
save it in a sort of abstract syntax tree...


However I look forward to taking a look at your implementation at the
link you provided.


Thanks a lot!


ciao :-)
Lorenzo
