D - Bug: Overloading, overriding and out parameters.

     void foo(out char c)
     {
         c = 13;

}

class B : A

     override void foo(out int x)

     }

     this()
     {
         char c;
         foo(c);
     }
}

A.foo(out char) isn't found in the B constructor.

The compiler errors out with the message 'cast(int)(c) is not an 
lvalue'.  It works fine if the out keyword isn't there.

Look at Walter's answer to my message
"BUG?: opIndex in opApply" from the
6th of November. It probably isn't a bug, but
something to do with the reference nature of 'out'.
