From Brian Harvey:
I admit it's been a long time since I've worked on this, so maybe I'm missing something, but the reason for using valid_pointer() is that if a node is of type other than pair, the car/cdr/obj of that node may be something other than a pointer to a node, e.g., a pointer to a character string, or the address of the continuation of a special form.
