Currently we only diagnose it once the adaptor is used in a pipeline. This adds static assertions to diagnose it immediately. libstdc++-v3/ChangeLog: PR libstdc++/112803 * include/std/ranges (ranges::to): Add static assertions to enforce Mandates conditions. * testsuite/std/ranges/conv/112803.cc: New test.
