--- Comment #7 from Diego Franco <di...@franco-technologies.com> ---
This works:
#include <vector>
#include <cassert>
struct A
{
operator const int&() const
{
return a_;
}
int a_;
};
int main()
{
A a {};
const auto& b1 {static_cast<const int&>(a)};
const int& b2 {a};
assert(&a.a_ == &b1);
assert(&b1 == &b2); // works
