The code I gave you earlier today is from a make-believe universe
where C++ has reflection (in the namespace std::Reflection). Using the
make-believe reflection features, the constructor of
std::function_defargs can get the default arguments from the function
pointer (note that the constructor is consteval).

Not sure what you're saying here. My code shows how it would be
possible to compose the class 'std::function_defargs' using reflection
features.
