I guess I'm just allergic to ref-passing variables that you cannot see declared
anywhere. In your example, C c1 is explicitly declared; in the original
example, it's implicitly declared by the method call. IMO, implicitly declared
variables should always be rvalues, but I guess that's a lost cause.
