[swift-dev] [stdlib] Array.description calls debugDescription on its contents

while I was working on this <https://github.com/apple/swift/pull/348> PR I encountered unexpected behavior from Array.description. It iterates over its items and calls debugDescription on them. I found it a bit unexpected thus my question here. Is it desired behavior? I would expect description and debugDescription call respective methods on the contents.

(I asked the same question in the PR but thought it’s general, so might be worth posting here)
