Past and Present of Haskell – Interview with Simon Peyton Jones

Simon Peyton Jones discusses the history, design, and future of Haskell, the Glasgow Haskell Compiler, and functional programming in industry.

Some time ago, we got a fantastic opportunity to interview Simon Peyton Jones, who was a key contributor to the design of Haskell and one of the lead designers of Glasgow Haskell Compiler (GHC). Right now, Simon is working at Microsoft Research, where he researches functional programming languages. In the interview, we discussed the past, present, and future of Haskell, Haskell’s benefits and downsides, GHC, walking the line between Haskell being a research and industry language, and multiple other topics.
