I could see a case being made that programming language functions, especially in ruby where everything is message passing, forms a package manager. A method might actually want to guarantee that when it sends a message foo that the code receiving it remains fixed. Being able to declare dependencies that granular might actually be great for doing refactors and upgrades. Maybe we accepted too easily that dependencies for a project are global.
