It is time for Cone to get a proper module system. This design space is complex and rife with historical missteps. In order to distill the topography of the landscape and clarify the key requirements, I felt it necessary to begin the journey with cross-language research and contemplation. I wound up pursuing three rabbit-chasing adventures in module wonderland: What do programmers want from modularity? You can read about this adventure in my earlier post on modularity, which captures what we want from modularity, and summarizes how the three modularity capabilities are surfaced across different layers of programming language features (and program decomposition).
