Well nearly every example of dip by RCM on comp.object and his first
one in C++ Journal *did* mention modules, or packages.

In fact dip would be nothing but Strategy pattern without RCM's shell
game of placing the client and server interface into the same unit
versus the concrete class in another unit.
