I agree. And, some simpler templating techniques may be used to map the
current helt type discriminator to the (C++) type, thus dispatching
calls by other means than what is typically referred to as 'visitation'.
(I still fail to appreciate the usefulness of those compile-time static
strings. I find them rather ugly...)
