Dear GHC developers, This year's ZuriHac 2021 [1], online Friday 18th June to Sunday 20th June, will again feature a dedicated GHC track to foster contributions to GHC and teach newcomers how to participate in GHC's development. For that we need your help: We would like to invite you to organize a session in the GHC track. This could be in form of a presentation, a workshop, or a hack session with topics centered around GHC. For some inspiration, these are the subjects from last year's track: - Write a GHC extension in 30 minutes, by Richard Eisenberg - A tour of linear types and linear base, by Divesh Otwani - QualifiedDo: customizable 'do' syntax without fuss, by Facundo Dominguez - On "simple" constraints for typechecker plugins, by Nicolas Frisby Please let us know if you'd be interested in leading a session or a workshop. You can contact either Niklas or myself, on this list or by private message. Best, Andreas and Niklas ZuriHac 2021 GHC track coordinators [1]: https://zfoh.ch/zurihac2021/
