To have it short: With the syntax of C/Java and scripting features, what does this language differentiate from JavaScript?

There are some nice features added, but I think that some of them are also covered by newer JS versions. I really don't want to argue to much about JS, but other persons will ask the same question, I guess.

The line "optional 16bits characters strings" also makes me worry a little, since I know how much trouble an alternate approach (8bit strings vs. Unicode) there is in Python (which led to major changes in Python 3). It just makes to much headaches.

If the author is reading here, you might also consider linking to a page of your personal website, that is accessible (I get directory listing denied).
