I exactly said this would require program analysis as a whole, at the co=
st  =

of separate compilation, and thus also at the cost of dropping any kind =
of  =

library, either shared or static. If any type is potentially the root of=
 a  =

class, then you have to avoid dynamic dispatching every where possible, =
 =

and to do so, you need global analysis. If you don't, you get the direct=
  =

performance issues, typical of interpreted languages.

But I may be wrong if I am not replying to what you had in mind (not sur=
e  =

anymore I understand the topic).
