I was going to say something about into() here but the topic has morphed to sequential()? yes, true. I agree with Brian that into is not as great as it can be but I think the problem is the interface Destination that into uses.

Maybe we are focusing on different problems, but to me the main one is a spec/expectations clash: For user-friendliness, we want relevant properties of sources to be preserved in destinations. But for generality, we want anything to be put into anything. This shows up mainly in orderedness, but you can imagine users "expecting" any other property as well (like sortedness wrt a comparator). I think this is a no-win situation.
