This seems a very cool and interesting evolution for a stable and productive language, focused on real needs in the industry. The focus on making sure it all integrates well and works with legacy code is astounding. Very nice. Ocaml future seems great.

My compiler's coming long nicely. If anybody's keeping track (and thank you for that) expect an alpha release version by Friday next week by the latest
As of now I've decided on the name "Unimal," short for "Universal Machine Language" to pay homage to older languages and because I gave Unimal an older syntax model.
The first official release will compile to a custom bytecode I hope to develop before then.

Have a good day everybody
