I'm curious about VM support for immutability. I think it's a really interesting idea whether low level runtime support can significantly enhance performance of immutable data structures - is that what you're suggesting? Would you be willing to expand on it? (My perspective: I am turned off by any language that doesn't have a JVM implementation because I have so much knowledge and trust of that runtime. But I have to acknowledge, byte-code level support for immutability is thin to non-existent).
