Fan -- Another New Java

Fan has recently been doing the rounds and i spent some time looking at it. It appears to be pretty much in the same space as Scala in most aspects. A deeper look at Fan reveals some interesting points. Similarity with Scala is it runs on the vm, has both dynamic and static typing, closures, mixins are built in etc etc. However a few interesting features in Fan over and above these are
1) Core support for the JVM, CLR and Javascript in the browser.
2) No support for global variables
3) Almost Erlang like concurrency semantics
4) Types are non nullable by default
5) Simpler namespaces and less verbose API's
6) JSON like serialization
On the while it appears has a groovy like simplicity with all the power of scala.
