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...)
