           Summary: Allow overriding of private/package class methods
           Product: D
           Version: D2
          Hardware: All

"Symbols with private visibility can only be accessed from within the same module. Private member functions are implicitly final and cannot be overridden."

This makes no sense as a derived class in the same module can "see" the method.

Also, the spec says nowhere that `package` visibility functions aren’t virtual or abstract, but one get the error message: "function `A.f` `package` functions cannot be `abstract`" And they cannot be overridden.
