Sorry, the example should have been:

enum cc = cast(char[])"hello";
enum ss = cast(string)['a', 'b'];

void main()
{
    auto cc1 = cc; //*Should* duplicate
    auto cc2 = cc; //*Should* duplicate
    auto ss1 = ss; //Should *not* duplicate
    auto ss2 = ss; //Should *not* duplicate
    assert(cc1 !is cc2); //Failed to duplicate
    assert(ss1  is ss2); //Failed to not duplicate
}
