I agree. It also grants safe way to pass temporaries:
int bar();
int* gi;
void foo(ref int i)

foo(bar()); // unsafe


Well rvalues still shouldn't bind to temporaries because I want to allow 
a function to return by ref a ref parameter:

ref int foo(ref int i)
{
    if (i == 0) ++i;
    return i;
}

Binding an rvalue to a ref would essentially pass a zombie out of foo.
