Hi there, folks!
I had this issue while working on a stateful metaprogramming technique
(almost complete):
"is_scoped_enum_v is not a member of std"
https://godbolt.org/z/jqzdf4rvq
as you can see, I am using c++23 and according to:
https://en.cppreference.com/cpp/types/is_scoped_enum
it says:

template< class T >struct is_scoped_enum;

(since C++23)
yet I am getting "a not found error". Any discussion on the potential
issues would be appreciated and even more so if such discussion targets
other issues in my technique/approach. I personally believe that this error
is caused by some implementation issues, but what made me discuss this over
here is that I face this issue in MSCV and in godbolt.
