First, thanks for the interest!
Actually the language is pretty stable, and I take the (rare) breaking changes seriously... at least seriously enough that I write extra code to help users migrate through the change.
The main blocker for commercial use is that I've deliberately used a CC non-commercial license to emphasize that it's an experiment and so make it clear commercial use isn't yet allowed. I expect to change that soon though, as I think it's about ready for "alpha use-at-your-own-risk" Apache-licensed commercial use. We'll see, I have a couple more things I want to achieve in the coming weeks before calling it "0.8" and switching to a commercial-use-allowing license...
it's been three months, so maybe we're now close to a commercially-viable-ish version? even though 0.8 hasn't been released yet
