Episode notes
Message Indirection in OO
- Messages in OO provide a layer of indirection, enabling polymorphism and hiding implementation details.
- This separation of caller and callee allows for flexible system evolution and late binding.
OO's Reversed Dispatch
- OO reverses the dispatch order of FP by prioritizing the value's class over the function.
- This allows the value to determine the operation, enabling open-world assumptions and ad-hoc case additions.
Open-World Assumption in OO
- OO's value-centric dispatch eliminates the closed-world assumption, enabling seamless integration of new classes.
- Each message pass cleanly separates caller and callee, promoting modularity and independent modification.
