[etc.]

Can I ask why all the functions have different names? Wouldn't it be
more natural to give them all the same name and then overload on the
argument type?

If they all have the same name then instead of calling it traverse,
it could be operator(). Accept code could then look like:

virtual void accept(Traversal &t) { t(this); }

I suspect a reference to a Traversal is more helpful than a pointer
as references can't be NULL and there's no need to rebind t partway
through a function.
