Yes i know this has nothing to do with `std::bind`. For example, I created the
following demo that reproduces the same error without std::bind. See demo:
https://godbolt.org/z/K6jKqsGx5 . I also mentioned the same in one of my
comments here:
https://stackoverflow.com/questions/74385849/clang-accepts-program-involving-requires-constraint-while-gcc-and-msvc-rejects-i/74386905#comment131319278_74385849
. I've edited the title of this bug.
```
template <typename T>
class myclass {
public:
void func(const T&) requires true
{
std::cout << "true";
}
void func(const T&) requires false
{
std::cout << "false";
}
};
template<typename T>
void bar(T&& )
{
}
int main(){
myclass<int> obj;
bar(&myclass<int>::func); //accepted by clang but rejected by gcc and msvc
}
```
