Well, it _is_ debatable as to whether that's desirable or not. With the 
current behavior, you can have a package which shares stuff within itself but 
not with its sub-packages, but there's no way to share with the sub-packages 
without making the symbols public; whereas if sub-packages have access to 
their parent packages' package functions, then packages _can_ share with their 
sub-packages, but they can't restrict anything to just the package. Both ways 
have their pros and cons. I don't know which is ultimately better.
