Interesting. This states that the order is never updated: when an existing element is overwritten, it is not moved to the end. Only new keys are appended. This allows for a more efficient implementation (such as suggested by Levente).

I think an OrderedDictionary would most often be used to preserve the original order of keys. Assigning a new value should not move the item to the end.
