It's a bit interesting that I initially stumbled on Oberon+ while searching for something typed which compiles to straight Lua and was surprised seeing the scope of the project.
In any case, I wish you all the best in the development of the language!

When designing a language, it's hard to get rid of the initial sins, so if in doubt, leave a feature out, so you don't regret it later; once enough people are involved with the language and writing code with it, any change that isn't backwards compatible is an imposition on everyone involved.
Playing the devil's advocate: On the other hand, making a whole new language is rarely a way to GTD now, it's usually an investment in the future. For surviving into that future the language usually needs the involvement of the community. And for that one has to consider what new/different/radical things does the language offer to the public to hook them on. May be it's OK to sin a little and get straight closer to v1.0? Of course, a few will hurt but they'll live.
