mclow.lists created this revision.
See https://wg21.link/lwg2946 for details.
This issue has not yet been adopted by WG21, but I implemented it to make sure
that there were no problems in the proposed resolution.
It turns out that there was. Making these changes lost the ability to construct
a `basic_string` (w/o template parameters) from a `string_view`; i.e, the
implicit deduction guides were no longer sufficient. So I added a couple of
explicit deduction guides.
This will not be committed until after WG21 has approved this resolution.
