Effekt

As opposed to the other members of the Effekt family, Effekt is a new standalone language. It extracts the essence of most of the other embedded language variants in a simple core calculus.

The language Effekt attempts to close the gap between research languages with effect handlers and languages for working programmers. The design of Effekt revolves around a different view of effects and effect types. Traditionally, effect types express which side effects a computation might have. In Effekt, effect types express which capabilities a computation requires from its context. This new point in the design space simplifies the treatment of effect polymorphism and the related issues of effect parametricity and effect encapsulation.
