In the following code, ref storage class of function foo's parameter s is
ignored.
So calling foo with lvalue makes confusing.
----
int foo(S)(ref S s){ return 1; }
int foo(S)(S s){ return 2; }
void main()
{
    int n;
    assert(foo(n) == 1);  // Line 6
    assert(foo(0) == 2);
}
----
test.d(6): Error: template test.foo(S) foo(S) matches more than one template
declaration, test.d(1):foo(S) and test.d(2):foo(S)
