Well, it makes perfect sense to me, once given that in D, 'private'
allows access from anywhere in the same module, rather than only in
the defining class.  I agree that it's weird and surprising in C++.

Are 'package' qualified functions also non-virtual?  The documentation
  http://d-programming-language.org/function.html#virtual-functions
says that "all non-static non-private non-template member functions
are virtual", but I get the same sort of linker errors with 'package'
functions that I do with 'private' ones, even with code that's all in one
module.
