We should chat more about Reminders v2 - I want to learn more about what you'd like it to provide. Can you comment on the issue (https://github.com/dotnet/orleans/issues/7573)? If you'd like to see some of what is in the works, please message me on Discord and we can chat more about it (https://aka.ms/orleans/discord)
List expressions I'm overly excited about. Can't wait to use and of course dictionary expressions will be amazing in the future.

The using enhancements. Hopefully I don't end up overusing tuples.
If Orleans had secretly been working on reminders v2 it'd be early Christmas.
