At present there's going to be one: "main" repeated many times but I think Walter promised us another one soon...

About this, Walter had proposed the following: "I'd suggest adding a virtual method GetMainSymbol to the Language.h interface, which could be implemented by each language plugin.". I guess it's a good approach. What are your thoughts?
