Why would you expect stability from software in early alphas is beyond me. If you want to be an early adopter you need to take the maintenance problems into account. And if you just wish to use a somewhat completed language you should have just waited for a final release.

PLs are complicated beasts and developing them takes time. It's normal for a language to change drastically during development: frequently it turns out that some feature doesn't fit well with some other, and you need to scratch the feature or redesign both features.
