[antlr-interest] How viable is the Csharp3 target? (more specific questions)

[Jim Idle]

System.out.println("invoke "+$ID.text);}

Is Java code, which is why I encourage you to just use ANTLRWorks with
Java to get your head around ANTLR, then you will be able to see the woods
from the trees switching to C#.
