It requires TYPE tokens when you have definitions. However, the lexer will produce an ID token unless you look it up in a table. So this is feedback from the 'typedef' to the lexer. So we at least need feedback to the lexer from the parse. I know we need feedback from cpp to the lexer. I will think of it.
