A string could be considered unused when its length is set to 0. Memory would need to be dynamically allocated in small blocks. The API should return "no method for string" if the external doesn't implement strings.
... which wouldn't get us true strings in the mathematical sense of a free monoid <Alphabet,concat()>, since the empty string is the identity element for concat()...
