Hi Simon, Yes, an AMA sounds like a great idea! Yes, absolutely, we could collect some questions ahead of time and then also give people the opportunity to submit questions during the event.

Andreas, Niklas

Would an “ask me anything” slot be useful? We could get a handful of GHC devs (eg me) together and invite participants to ask about GHC specifics. Not so much personal “how long have you worked on GHC?” but more technical “how does class instance lookup work?”.

I’d be willing. But it could fall a bit flat if no one asks anything… maybe prime the pump with one or two questions…

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
