It's great that Temporal is coming, and I'm sure there are bunch of other nice things coming up too, but unfortunately I don't share your optimism with the specific proposals that you mention (even though those would be very nice).

Pipelines, pattern matching and records+tuples have all been in the works for 4+ years, and are all still in stages 1-2. I don't think any of them has seen any significant progress in the past year, except maybe pattern matching. According to an issue in the records and tuples repo, there's been pushback on the value semantics of it (i.e. whether === can be made to work). Dropping value semantics would significantly reduce the whole proposal's usefulness.

I think all of them are at least a year or two away from reaching stage 3, if they ever do. But hey at least we now have array grouping functions.
