Providing an additional method of set() allows for the ability to ignore duplicate keys so that it feels more like dict[key] = value. It might be interesting to provide this as a selectable behavior within an additional constructor's arguments. <div class=""><br class=""></div><div class="">Dictionary(allowDuplicate: true, pairs: <span style="background-color: rgb(255, 255, 255);" class=""><span style="white-space: pre-wrap;" class="">[("z", 1), ("z", 2), ("z", 3), ("z", 4)]) so that the dictionary behavior remains in line with the compile time checks.</span></span></div><div class=""><span style="background-color: rgb(255, 255, 255);" class=""><span style="white-space: pre-wrap;" class=""><br class=""></span></span></div><div class=""><span style="background-color: rgb(255, 255, 255);" class=""><span style="white-space: pre-wrap;" class="">Gregg</span></span></div><div class=""><br class=""></div></body></html>
