> Consider the following scenario: 
> declare trait A 
>   sub : int 
> end
> declare X end
> declare trait Foo
>   fld : A
> end
> declare Bar
> @Traitable( logic = true )  // new mode
>   fld : X
> end
> If an instance b of Bar is traited with Foo, the value of its field "fld" 
> should in turn be traited with A.
> Truth maintenance and transparent casting are required. 
> The goal is to write rules such as:
> when Foo( fld isA A, fld.sub == 0, .... ) then ..
