Test case:

----------------
void s6391(ref double x){}
void bug6391() {
    double d = 1;
    s6391(d.im);
}
----------------
x.d(4): Error: function x.s6391 (ref double x) is not callable using argument
types (double)
Error: 0 is not an lvalue
----------------

With template methods, it becomes hard to trace back where is the cause of this
line-less error, e.g.

------------------------
void t6391(R)(ref R x){
    if (x.re > 0)
        t6391(x.im);
}
void bug6391b() {
    double d = 1;
    t6391(d);
}
------------------------
Error: 0 is not an lvalue                                              //
where?
x.d(7): Error: template instance x.t6391!(double) error instantiating  // why?
------------------------
