"There's a good an bad side to modules: Good: Provides a unit of compilation, a unit of code distribution. unit of code replacement" I think that Joe ignores the major rationale for modularization. Modules provide the way to cut out the fragment of a complex project and apply local reasoning to it. In other words a module is the way to "divide and conquer" the complexity that crosses the border of the single mind's capacity. As such a module is not about code compilation, distribution and upgrades. It's about human cognitive abilities.
