Editing The Sketch of a Polymorphic Symphony

Title: The Sketch of a Polymorphic Symphony

Research Question: How can functional strategies, a form of second-order polymorphism, be used to create a model for parameterized and typed strategic programming?

Methodology: The authors propose a model of functional strategies, a first-class generic function that can traverse into terms of any type while mixing uniform and type-specific behavior. This model is characterized by three key features: first-class polymorphism, run-time type case, and a fundamental combinator for folding over constructor applications.

Results: The authors present two original forms of parameterization. Firstly, they design parameters for the specific control-flow, data-flow, and traversal characteristics of more concrete traversal schemes. Secondly, they use overloading to postpone commitment to a specific type scheme of traversal. This results in a portfolio of traversal schemes that can be viewed as a challenging benchmark for setups for typed generic programming.

Implications: The model and suite of traversal schemes developed in this paper suggest that parameterized + typed strategic programming is a potent combination of parametric, intensional, polytypic, and ad-hoc polymorphism. This could have significant implications for the field of typed generic programming and the development of more flexible and expressive programming languages.

In conclusion, the Sketch of a Polymorphic Symphony presents a model for functional strategies that could potentially revolutionize the field of typed generic programming. By using first-class polymorphism, run-time type case, and a fundamental combinator for folding over constructor applications, the authors create a parameterized and typed strategic programming approach that is both flexible and expressive. This could lead to the development of more powerful and versatile programming languages in the future.
