Following code doesn't work.

template isFunction(X...) if (X.length == 1)
{
    enum isFunction = true;
}

struct S
{
    static string func(alias Class)()
    {
        foreach (m; __traits(allMembers, Class))
        {
            pragma(msg, m);  // prints "func"
            enum x = isFunction!(mixin(m));  //NG
          //enum x = isFunction!(func);  //OK
        }
        return "";
    }
}
enum nothing = S.func!S();
