This patch fixes the ref_view branch of views::as_const to correctly query its underlying range type X. PR libstdc++/119135 libstdc++-v3/ChangeLog: * include/std/ranges: Include <utility>. (views::__detail::__is_ref_view): Replace with ... (views::__detail::__is_constable_ref_view): ... this. (views::_AsConst::operator()): Replace bogus use of element_type in the ref_view branch. * testsuite/std/ranges/adaptors/as_const/1.cc (test03): Extend test.
