GB277 24.04 Conflict of istream_view and view requirements P1456 #273
Description
Adopt P1456 or change istream_view's requirements
P1456 weakens view so that it does not require copyable. Without this, istream_view is unable to process non-copyable types as input.
LEWG approved P1456 in Kona, but it seems that it didn't make it in time for LWG in Cologne. I don't think this is something that can be fixed in C++23.
Proposed change:
Apply the proposed wording in P1456 to the International Standard.
