This project is no longer under active development. We've made Skybison publicly available in the hopes that people might find its history and internals interesting, or maybe even useful. It has not been polished or documented for anyone else's use.
We cannot commit to fixing external bug reports or reviewing pull requests. That said, if you have experience in dynamic language runtimes and have ideas to make Skybison faster; or if you work on CPython and want to use Skybison as inspiration for improvements in CPython, feel free to leave a note in a GitHub issue.
Instagram is now developing Cinder.
