You can write "A * B" and depending on nature of A, that would be a declaration of B as pointer to type B, or multiplication of A and B. You could say that this multiplication would be 'void' (as in 'not assigned to anything') and I could come up with even more complicated example, like "A * B();" where this is either function declaration or multiplication of A and function named B() with side-effect let's say. But that's not the point: if parser has to do heuristics like that to parse language properly, it is already context-dependent or at least not LALR(0) or LALR(1).
