That's a lot of goodies in a new release! It seems it is outpacing the JVM's development...

Apart from [the equivalent of] records, I see nothing big.

Except...

this '''let! a = fetchA() and! b = fetchB()''' really puzzles me. Does C# have a high-level syntax for concurrency timing? [something that Java is strongly lacking, and that Typescript did solve with Promise.all(), which is an ugly syntax, from my perspective]

Any elaboration on this is very welcome.

The inlining and escape analysis changes are fairly big from a performance perspective.

Also, C# doesn't need nearly as many massive changes like project Valhalla because they got a lot of those design choices right from day 1 (mostly by looking at what Java did that was dumb and avoiding it).
