non-class rvalues always have cv-unqualified types
- by FredOverflow
§3.10 section 9 says "non-class rvalues always have cv-unqualified types". That made me wonder...
int foo()
{
return 5;
}
const int bar()
{
return 5;
}
void pass_int(int&& i)
{
std::cout << "rvalue\n";
}
void pass_int(const int&& i)
{
std::cout << "const rvalue\n";
}
int main()
{
pass_int(foo()); // prints "rvalue"
pass_int(bar()); // prints "const rvalue"
}
According to the standard, there is no such thing as a const rvalue for non-class types, yet bar() prefers to bind to const int&&. Is this a compiler bug?
EDIT: Apparently, this is also a const rvalue :)
