Anton Zhilin: That is one of the points if I’m not mistaken. Sealed
means that with whole-module-optimization the compiler can optimise
more things as it can treat it as final for other modules.

L. Mihalkovic: Could you give an example of what exactly do you mean?
I know one of the reasons behind the proposal is to actually improve
those situations by forcing us to think more on customisation when
designing APIs.
