  Anyways, my conclusion is. In most cases it IS an anti-pattern. Only if the, let's say "observing" function (the one that decides on the type), is really just observing the behavior nad trying not to interwind with the mechanics of the actual structures is it justified I think. In that case it provides greater cleanliness of your code. In this case though, as this is the ast package, and walking is a standard functionality of an ast, I think this could just as well be implemented with interfaces.
