But why does the user need to know about it? When presented this way,
it's just an implementation detail. When would the user ever actually
want to create and use objects of type code_unit_sequence directly? If
the only use of this class is as backing storage for
code_point_sequence, there is no need for it, especially since, as you
said, there are already plenty of viable alternatives. If you say that
basic_string can do this job just fine, what is a strong motivating
example for adding another specialized sequence container type?
