ok. changing the rule then:
C() is S == true
foo(x) acts the same way as foo(x.super)
bar(&x) acts the same way as bar(&x.super)
i am not quite sure i am getting the answers along the lines of "use
protocol forwarding" instead. i have no protocol to begin with. for a
preexisting value type (e.g. OS provided) it would be a nightmare to create
and maintain the corresponding protocol.
