digitalmars.D - Protection in BaseClassList: semantics undefined?

Hi,


http://www.digitalmars.com/d/2.0/class.html

In the grammar specification I read that a base class or interface name can be
prepended a protection attribute. But I don't find a word about the semantics
thereof... Can anyone tell (and update the docs)?


Regards,

Harry

As far as most people can tell, it's an artifact from very early on in D's development. It was probably originally supposed to have MI but that was dropped. The compiler accepts public/private/protected on the base class but it's useless as it breaks things.
