Or the implementation can have a switch to choose between keep-first logic or replace logic. The latter seems a bit odd to me. The key position would be determined by the first encountered while the value would be determined by the last encountered. Starting with [(10, v1), (20, v2), (10.0, v3)], the ordered dictionary's items would look like [(10, v3), (20, v2)].
