It is like protected, but restricts it to classes in the current module.
This is useful at times, if you have a well known hierarchy that should
not be extended by third parties.

Whether this is good design or not, is debatable, I had some use cases
where it made sense for me. Regardless, I don't see why the language
should disallow it, except for performance reasons because virtual is
the default. If this default is changed, I really see no reasons to
disallow it.
