The P2499R0 paper was recently approved for C++23.
libstdc++-v3/ChangeLog:
* include/std/string_view (basic_string_view(Range&&)): Add
explicit as per P2499R0.
* testsuite/21_strings/basic_string_view/cons/char/range_c++20.cc:
Adjust implicit conversions. Check implicit conversions fail.
* testsuite/21_strings/basic_string_view/cons/wchar_t/range_c++20.cc:
Likewise.
(cherry picked from commit 2678386df2cc3505da85e95643327aa928e66a8e)
