Swift *explicitly* leaves this choice up to the TextOutputStream-conforming type. That is, the behavior is up to the receiver and not the argument of a call to `TextOutputStream.write(_:)`.</div></div></blockquote><br class=""></div><div>I feel like I must be misunderstanding what you're trying to say here, because I *think* what you're trying to say is that `TextOutputStream.write(_:)` is what decides whether to add the terminator, which is not only totally wrong (see <a href="https://github.com/apple/swift/blob/adc54c8a4d13fbebfeb68244bac401ef2528d6d0/stdlib/public/core/Print.swift#L260" class="">https://github.com/apple/swift/blob/adc54c8a4d13fbebfeb68244bac401ef2528d6d0/stdlib/public/core/Print.swift#L260</a>) but doesn't even make any sense since there's a terminator parameter on `print` but none on `write(_:)`.</div><br class=""><div class="">
