Project mention: Modern concurrency approaches on the JVM: Coroutines and Loom | dev.to | 2026-06-02
A coroutine is a lightweight thread that is managed by the Kotlin runtime. Coroutines were initially proposed in Kotlin version 1.1 M01, released in 2017. The first stable version was released with Kotlin 1.3 one year later.

carbon-lang
Carbon Language's main repository: documents, design, implementation, and related tools. (NOTE: Carbon Language is experimental; see README)
I can't speak about Dart, but Carbon had just barely started development when it was first announced 4 years ago, and is currently presented as an experimental language that is not yet ready for use [0].

which can include type assertions but also a lot more. The agents seem to do well with this.
I've also had good results using agents to write Crystal https://crystal-lang.org/ which is Ruby-like but does have the static types and produces blazing fast static binaries. Might be a sweet spot for coding agents if you're building some backend services. But I'd still pick Ruby on Rails for a new full stack project.

Stream.pipe() method gives a way to pipe the streams into a stream consumer object. To do that, one must implement a new class using the StreamConsumer abstract class. A good use case can be found in tests/lib/async/slow_consumer_test.dart.

Lua
Lua is a powerful, efficient, lightweight, embeddable scripting language. It supports procedural programming, object-oriented programming, functional programming, data-driven programming, and data description.
Seems similar in impact to https://nvd.nist.gov/vuln/detail/cve-2021-32626, I wonder why this has a CVE 10.
This code also looks generally fixed in Lua5.4, https://github.com/lua/lua/blame/9ea06e61f20ae34974226074fc6.... Valkey and Redis really need to move to Lua that isn't so old.
