What's next
ProcessKit is published for Rust as processkit on crates.io. Its first cross-language binding is also available for Python as processkit-py, with a separate overview on this site, a full guide set, and a source repository.
The longer-term plan is to bring the same approach — kernel-backed whole-tree containment, honest error semantics, and testable seams — to Go, F#, and Kotlin. Each implementation will follow the same philosophy and receive its own language-appropriate documentation.
