Keep the bool constructor public and mark it deprecated, so existing code that spells mod_gil_not_used(false) still compiles. mod_gil_used() now sets the flag through its friendship, which keeps the deprecated constructor the only bool overload and stops pybind11 warning against itself. Also use the py:: alias in exo_planet_pybind11.cpp to match its sibling home_planet_very_lonely_traveler.cpp. Assisted-by: ClaudeCode:claude-opus-5
test_smart_ptr.cpp and standalone_enum_module.cpp came from master after this branch was written, so they still invoked variadic macros with no variadic argument. That is a pedantic error below C++20. Assisted-by: ClaudeCode:claude-opus-5

Description
Seeing if I can reproduce the warning-as-error in iminuit (scikit-hep/iminuit#1100). I seem to have failed, but at least we can pass pedantic now for earlier C++ versions. This was mostly working around the trailing comma issue that goes away in C++20.
I've added a new way to spell
py::mod_gil_not_used(false):py::mod_gil_used(). If we ever were to change the default (which might make sense if free-threading becomes default), it would be good to have a (nice) way to specify the previous behavior.Suggested changelog entry:
py::mod_gil_used()as replacement spelling topy::mod_gil_not_used(false).📚 Documentation preview 📚: https://pybind11--5797.org.readthedocs.build/
