Hi folks !

I was using ANTLR to write a little code generator.
C# is the natural language of my programs.
So I though a C# Parser would be more powerfullto do some of my app specific
I also use customized AST tree construction in my parser.
something like :
     ! LPAR RPAR { #args = #[VOID]; }
     |! (LPAR VOID RPAR)=> LPAR VOID RPAR { #args = #[VOID]; }
     | LPAR! argList RPAR!
 { #args = #([PARAMS, "args"], #args); }
but I have some trouble with this contruction semantic:
"#args = #[VOID];"

as it generate:
args_AST = (AST)astFactory.create(VOID);
whereas it should generate (in C#, as it is correct in Java)
args_AST = (AST)astFactory.create(MyTokenTypes.VOID);

that's very curious.
I use this syntax more than once, but it write this uncorrect output only
my grammar file is relatively short, I could send it to whoever is
interested, if needed....
