I was thinking more broadly than basic_cstr_write which I happened to
quote. I may want my template classes to operate on the return type
of any writer in a consistent manner. This is possible if they adhere
to ContiguousRange and SizedRange as suggested.

Assuming the buffer is contiguous, begin == end - size, so there would
be no need to store an extra pointer.
