This is fixed for equality operators but not relational operators
enum class E { Foo, Bar };
bool b2 = E::Foo E::Bar;

Is that even allowed for normal enums?

yes, unscoped enums will be promoted to int

With unscoped enums the similar code works because cp_build_binary_op applies
the default integral promotions to the enums, and winds up comparing two int
values. The promotions are not applied to scoped enums because

ok, even for the case i misunderstood the proposal: there are still some
problems with it, making it unuseable.
enum class E { elem };
inline bool operator== (E c1, E c2)
{
return (int) c1 == (int) c2;
}
int
--- Comment #1 from rbuergel at web dot de 2008-11-09 04:11 ---
extended testcase, this fails for other operators, too
enum class E { elem };
int main()
{
E::elem == E::elem;
E::elem != E::elem;
E::elem E::elem;
E::elem = E::elem;
E::elem
19 matches
