Oh man, I love BEAM VM's design. Just looking at memory allocators, handling iolists, binary blob referencing, schedulers spread over all the CPUs, async IO threads. Just discovering that I found myself nodding my heading often say "aha, that's a really good way to do it".

It is good to see Elixir work on it alongside Erlang. I don't think everyone will jump ship to Elixir. For example I like Erlang's syntax (I might be in the minority) but meta-programming and ease of access to BEAM for newcomers is great.
