Why AstNode

Hi All,
Sorry if my question might sound stupid but why do I need to create or subclass AstNode for my non-terminals?

you don't have to, but if you need to generate abstract syntax tree (AST) then you need all these custom nodes. Google and read about concrete/abstract syntax trees in parsing
