Today, 2023-08-17, at 1830 UTC (11:30 am PDT, 2:30 pm EDT, 7:30 pm BST, 20:30 CEST, …) we are streaming the ninth episode of the Haskell Unfolder live on YouTube.
The Haskell Unfolder Episode 9: GHC Core
After parsing, renaming and type checking, GHC translates Haskell programs into its internal Core language. It is Core where most optimisations happen, so in order to get a better idea of what your program gets compiled to, being able to read and understand Core code is quite useful. Core is in essence a drastically simplified and more explicit version of Haskell. In this episode, we will look at a number of simple Haskell programs and see how they get represented in Core.
About the Haskell Unfolder
The Haskell Unfolder is a YouTube series about all things Haskell hosted by Edsko de Vries and Andres Löh, with episodes appearing approximately every two weeks. All episodes are live-streamed, and we try to respond to audience questions. All episodes are also available as recordings afterwards.
We have a GitHub repository with code samples from the episodes.
And we have a public Google calendar (also available as ICal) listing the planned schedule.
