Haskell in Leipzig 2017 opened its gates for everyone interested in Haskell and generally functional programming. Expect a great day of talks, tutorials, and a performance with a focus on FRP, followed by a Hackathon. Register early and get your ticket at a reduced rate. Looking forward to meeting you in Leipzig. Continue reading →
Let me remind you that the submission deadline of Haskell in Leipzig 2017 is this Friday. We seek abstracts of about 2 pages length on anything related to Haskell. Looking forward to your contributions. 😉 Continue reading →
Haskell in Leipzig (HaL) is taking place again from October 26 to October 28, 2017 at HTWK Leipzig. If you have any interesting Haskell-related material to share, please consider submitting an extended abstract. Continue reading →

One of the most important ingredients of Haskell is its type system. Standard Haskell already provides a lot of useful mechanisms for having things checked at compile time, and the language extensions provided by the Glasgow Haskell Compiler (GHC) improve heavily on this.
In this article, I will present several of Haskell’s type system features. Some of them belong to the standard, others are only available as extensions. This is a write-up of a talk I gave on 31 January 2013 during the Theory Lunch of the Institute of Cybernetics. This talk provided the basics for another Theory Lunch talk, which was about the Constraint kind. Continue reading →
