Congrats, sounds amazing. Will AST interpreters continue to be supported?

Yes. After all even the bytecode DSL still uses helper nodes to store profiles. But the dispatch and control flow no longer goes through node execute methods but an optimized bc dispatch and managed instead of native stack. The latter makes continuations trivial.

This was made possible by the excellent work of Matt D'Souza, as well as Nikola Bebić, who developed the first versions of it.

Thanks to the reviewers @awoess.bsky.social , @eregon.bsky.social, Stepan Sindelar, @gillesduboscq.bsky.social, Matthias Neugschwandtner, and special thanks to @stefan-marr.de for early adopting it with TruffleSOM.

SimpleLanguage was fully migrated already. You can check out the specification here: github.com/oracle/graal... In progress for migration are GraalPy and GraalJS. GraalPy already passes all the tests. 🎉
