visit_optional() is to be called only between visit_start_struct() and visit_end_struct(). Visitors that don't support struct visits, i.e. don't implement start_struct(), end_struct(), have no use for it. Clarify documentation. The string input visitor doesn't support struct visits. Its parse_optional() is therefore useless. Drop it.
