Why is that? why must I leave it accessible somehow (even if it's
protected) to all derived class of my derived class?
See specs : https://dlang.org/spec/attribute.html#visibility_attributes
Symbols with private visibility can only be accessed from within the
same module. Private member functions are implicitly final and cannot
be overridden.
This is (slightly) different, as he's not overriding private member
functions. He's overriding public functions, and marking them as private.
I think the issue is more that private functions are not allowed to be
in the vtable (which is not exactly what the text says).
Besides, it would be weird to mark a public function private in a
derived type. All that is required is to cast to the base class and then
you can call it.
I swear I read a bug that discusses this exact issue...
