+        ## Important information
+        The author's time for processing GitHub issues is unfortunately very limited. Because of this, _nanobind_ cannot accept feature requests. Furthermore, questions should not be submitted here, please use the separate "Discussions" tab. I will unfortunately need to close feature requests or questions maquerading as bug reports.

+        function(s) that cause breakage. Please submit matched and complete C++ and
+        Python snippets that can be easily compiled and run to diagnose the
+        issue. If possible, make a PR with a failing test to provide a
+        starting point for me to work on.
