That is the immediat way I would solve this.  What we want to prevent
is accidental modification.  So the "(const char*)" belongs to the
accessor.  This tree_string is going to be put in a union where a
priori we do not know which is going to be accessed; so the
const cannot belong to the object.  However, we can make sure that
anybody who access that field have the illusion of non-modyfiability.
