When appending fails, the deque is left in changed state. I would do it in different way. First append new item (can fail), and then make circular shift (never fail). This also should be faster (up to 2 times). Most code can be shared between rotate() and circular shift operation. |

For now, I prefer to continue using rotate() as a primitive and am saving circular shifts for another day (likely when I start working on slices). FWIW, the only way for append() to fail is a memory error; in which case, I would ilke to stop doing any work at alll and return a soon as possible, even if it means leaving the deque in a reordered state. |

Then the patch LGTM except few nitpicks. |
