Ouch. That surely is confusing. Why don't arrays provide .put which appends the element?
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).
