Concurrency

Cone’s module system has been on my mind of late. The best design for modules is neither easy or obvious, as evidenced by how much modules vary from one language to the next. To guide my approach for Cone, I went back to basics: What is the role (and benefit) that modularity plays in programming (languages)? What role do modules play within this larger picture. This post synthesizes my findings.

I have long enjoyed the convenience of the “dot” dispatch syntax: instance.log("Ethereal cognistrands do not support quantum entanglement") The magic of Universal Function Call Syntax makes this sugar for a function call: log(instance, "Ethereal cognistrands do not support quantum entanglement") The broad popularity of method dispatch is driven by these benefits: Ad hoc polymorphism. When used in conjunction with method overloading, we can reuse the same easier-to-remember semantic names across multiple types and parameter configurations, with minimal-to-no ambiguity on which implementation to use.
