There is some pretty basic syntax in "use" to specify which items are exported to the current package. It doesn't work well with bundles (like "use PDL"), though.
I think we discussed going to a strict object mode (no exports) some years ago -- do any of the other old-timers remember that? My recollection is that nobody wanted it at that time, or at least nobody wanted it enough to actually do anything about it.
