package is only for modules in the same package, and a package is made up of all of the modules within a directory. Sub-directories are not part of the package. Sub-packages do not have access to package functions in their parent package, nor does a parent package have access to package functions in its sub-packages. Anything shared between them must be public. There is no way to give other packages (be they sub-packages or otherwise) access to a package's functions other than through public (or protected if you're dealing with inheritance). As for friend, D's solution was to make private be private to a module rather than a class or struct. So, everything within a module is effectively a friend to everything else in that module. package comes from Java. - Jonathan M Davis
