Agreed. For some reason it reminds me of something akin to:
_____________
#include <iostream>
struct foo
{
int a;
};
int main()
{
foo a = { 0 };
foo b = { 1 };
{
foo const& r = (true) ? a : b;
std::cout << &r << "->a = " << r.a << "\n";
}
{
foo const& r = (false) ? a : b;
std::cout << &r << "->a = " << r.a << "\n";
}
return 0;
}
