Well I guess most recent example is that `final` by default 
proposal - marking all existing functions as virtual ones 
explicitly.

Problem with dfix is that such tool can't afford to be "best 
effort" implementation if it is to be used as justification for 
breaking changes. It needs to provide guaranteed 0-cost 
transition or someone will be inevitably unhappy about the 
breakage anyway :(
