Our great sponsors
  • SonarQube - Static code analysis for 29 languages.
  • OPS - Build and Run Open Source Unikernels
  • Scout APM - Less time debugging, more time building
  • linear-base

    Standard library for linear types in Haskell.

    Handle is defined in terms of UnsafeResource (in linear-base). This is where the linearity checking "stops". If you pattern match an UnsafeResource then you have to make sure that you correctly close/free it. Luckily, this only has to be implemented once in an internal module and is not exported in the public interface.

  • koka

    Koka language compiler and interpreter

    Effects are a restriction of monads. Eff r is a monad, but not all monads can be written as Eff r. You can have algebraic effects without monads. In koka effects are part of the language itself. The restriction makes sure that it is possible to compose effects. And this composition of effects is also why the effects is called algebraic. And that is why we want to avoid monads in the first place: because they don't compose.
