According to C++20 standard the following code is valid, however it doesn't
compile with clang13:
enum class Pig { Oink };
using Hog = Pig;
using enum Hog;
Output:
<source>:3:12: error: type alias 'Hog' cannot be referenced with a enum
specifier
using enum Hog;
^
<source>:2:7: note: declared here
using Hog = Pig;
^
