A lot of simple changes could be made with little or no semantic 
analysis. I'm not talking about complex refactorings such as 
Extract/Inline Function, Introduce/Remove Parameter, Pull Method 
Up/Down, extract Class/Interface, etc.

Rather, simple fix changes that would be useful if the API or syntax of 
the language changes. That's why I asked for examples of dfix changes 
(even if for hypothetical language changes) - to see how easily they 
could be implemented or not.
