This project has been discontinued. But fear not, a new scala-native is on the way, Denys Shabalin a phd student at EPFL is working on completely new implementation of scala-native. His previous work, scala offheap, a way to use off-heap memory on the JVM with type- and memory-safety is very impressive.

Would native-compiled scala allow for some of the features that have been prevented by the need for Java semantic compatibility, like guaranteed tail call optimization?

Isn't this what the @tailrec annotation is for? If it compiles it's tail recursive. This is separate than actually JIT'ing the call bytecode into a loop, I realize, but for a pragmatic engineer there's already a solution.
@tailrec works only for simple cases of tail recursion. For example it doesn't support mutual tail recursion at the moment.
Yes, especially talking about better tail call optimisation.
Really looking forward to hearing this talk!
I wonder if there will be any potential for C++ interop. I would __LOVE__ to be able to code Scala that can be called from and in turn call C++ interfaces.
I mean, there's nothing stopping you from writing JNI wrappers; they work with anything that uses the JVM.
