This operator is a convenient substitute for the SetAt method. You can only use it on the left side of an assignment statement (an l-value). If there is no map element with the specified key, then a new element is created.
There is no “right side” (r-value) equivalent to this operator because there is a possibility that a key may not be found in the map. Use the Lookup method for element retrieval.
