Great question! I actually started working on my talk last week. I need to scroll a bit back to see the suggestions from last time, although they've been kind-of imprinted in my head.
I want give an overview of Arrow, so I don't want to waste too much times on things that have been talked about a lot. Without giving too much away I am currently planning on covering:
1. DSLs
2. Raise, AutoCloseScope/ResourceScope, ?
3. Context Parameters
4. Optics
5. Resillience
6. STM
Emphasising how everything works together, and how everything works together with the rest of Kotlin but I'll have to see how everything fits together. Any feedback, or requests are still greatly appreciated 🙏
