Basically, when you're using an array as an output range, you're
saying "Hey, here's a slice of memory to put the results in".
You're _not_ saying "hey, here's a bit of memory that I have
already, so put it on the end of it."
The behavior is technically correct, but output ranges probably
aren't being described as well as they could be. That said, the
concept is a bit unusual and strange to me as well. I love the
concept of InputRanges but I'd really like to see more coverage
on OutputRanges and how to work effectively with them (and,
especially, arrays as OutputRanges).
