By the way: the reason that I rejected the temporary-variable choice was that I couldn't really see the difference cost-wise between doing that, versus returning var.dup from front(). Especially as it's not necessarily guaranteed that front will be called frequently (I might just popFront() until the range is empty and then take the final front value).
