So, my tests seem to be telling me that the immutable design of `Iterator` is unacceptably slow in microbenchmarks compared to plain Java for iterating sequences. Which is pretty much what we expected, of course. We need to test a fork of Ceylon that uses mutable iterators and confirm this. Ohwell, it was worth trying, I suppose.
