My friend who works on Flow9 for something like two years was willing to answer questions, but his message did not get through the moderation in this thread I believe. Basically Flow is a functional language somewhat similar to OCaml (that's my naive understnding). It has multiple backends, and my friend who originally is a math teacher in university and develops theorem provers was hired to work on some of the backends, I think it was the Java backend. He is always so exited talking about Flow, and kept telling me for a about year that they are going to release it as open source and there is a lot of excitement because of that.
I wish they could build a community around this language at least as successful as OCaml's community is.
Sometimes comments get caught in spam filters. I'm not seeing any case of that here, but if your friend's comments aren't visible, please tell him to email us at hn@ycombinator.com so we can mark his account legit.
