Learning Prolog to be a better Haskell programmer

Posted on February 17, 2014 by Kwang Yul Seo

While learning some advanced topics of the Haskell type system, I found type level programming is reminiscent of logic programming.

For example, Fun with Functional Dependencies shows how to implement insertion sort using functional dependencies in a programming style similar to Prolog. Fun with Type Functions also shows a similar example using type families.

This similarity is not a coincidence because of the correspondence between a logic system and a type system, which is known as Curry-Howard isomorphism.
