--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
https://gcc.gnu.org/projects/cxx-status.html says that P1907R1 is supported
since GCC 9, which seems unlikely when P1907R1 wasn't approved until 6 months
after GCC 9.1 was released.
That page also says that the relevant feature test macro check is
__cpp_nontype_template_parameter_class >= 201806, which is wrong because the
check for P1907R1 is __cpp_nontype_template_args >= 201911, and GCC defines:
#define __cpp_nontype_template_args 201411L
I think it's a doc bug, and the feature is not implemented yet.
