Ok maybe I am wrong:

template unaryFun()
{
    void unaryFun(ref int a) pure nothrow @safe @nogc {}
    void unaryFun(int a) pure nothrow @safe @nogc {}
}

void unaryFun2()(auto ref int a) pure nothrow @safe @nogc {}

void main()
{
    int x;
    alias unaryFun!() u;
    alias unaryFun2!() u2;
    u(41);
    u2(41);
}


this works ok for u, but not for u2.
