When using old alias form, `ref` is both accepted and not making any effect:

-----------
alias ref int RefInt;

void foo(RefInt x)
{
    x = 42;
}

void main()
{
    int x;
    foo(x);

    import std.stdio : writeln;
    writeln(x);
}
-----------
0
-----------

`alias RefInt = ref int` is rejected with "Error: basic type expected, not ref"
so I assume it should be the same here.
