Not the original poster, and I don't have very high hopes that these will be revisited, but some things I would like to see revisited are:

- ability to define anonymous functions without having to put it inside an anonymous struct. I get the argument against closures (even if I don't fully agree with it), but not having first class support for anonymous functions feels pretty regressive for a modern language

- have a way to include payload data with errors. Or at the very least, define an idiomatic pattern for handling cases where you have additional data for an error

- allow struct fields to be private

- bring back async support in some form (this one I do have some hope for)
