Yes, as an example structured concurrency in Java (final release in Java 28 perhaps). I think that could totally change how we write concurrent code in that language.

I just upgraded a less important service to Java 27, a few days after its release (several nice features). It's cool how easy it is to upgrade nowadays.

That an agent writes most of the code doesn't mean anything to me here.

My examples are Java because that is the main language where I work.
