Abstract

Interface types are a useful concept in object-oriented programming languages like Java or C#. A clean programming style advocates relying on interfaces without revealing their implementation.

Haskell's type classes provide a closely related facility for stating an interface separately from its implementation. However, there are situations in which no simple mechanism exists to hide the identity of the implementation type of a type class. This work provides such a mechanism through the integration of lightweight interface types into Haskell.

The extension is non-intrusive as no additional syntax is needed and no existing programs are affected. The implementation extends the treatment of higher-rank polymorphism in production Haskell compilers.
