        <pre>This code does compile. If we replace (1) with (2), it does compile, which is
weird and likely wrong.

namespace N { enum E : int; }
enum N::E : int {A,B};

int bar() {
    //return int(::A); // 1
    return int(A); // 2
}

Clang reject the commented line in function bar(), but accepts the line below.
I think it should either accept both or reject both. Gcc does reject both. 

However, maybe compilers should accept both lines, because N4296 says in
7.2/11:
<span class="quote">> Each enum-name and each unscoped enumerator is declared in the scope that
> immediately contains the enum-specifier.</span >
which is to global scope.

The problem originally appeared in this SO question:
