effect-system

Effect polymorphism allows functions to operate across varying effect contexts without rigid type constraints. By leveraging row types, the system flexibly combines and tracks multiple side effects, ensuring type safety while maintaining code reusability.

Effect checking automatically verifies that functions adhere to their declared effect constraints during compilation. This mechanism enhances program safety by ensuring no undeclared computational impacts occur within purely functional code.

Yes, implementing an effect system typically requires a type checker generator as a prerequisite dependency. This foundational tool provides the necessary infrastructure to parse annotations and enforce type-level effect rules.

Standard type systems track data values, whereas effect systems specifically track computational side effects. By annotating types with effects, this approach provides deeper reasoning about program purity and security that standard type checking cannot achieve.

Yes, effect handlers are supported to manage side effects in a Haskell-like language. You can implement an effect system that clearly marks and handles I/O operations, ensuring functions interacting with the outside world remain controlled.
