In Python, the default values of parameters are evaluated only once during their declaration. So, whenever the default parameter is used the same object will be used. Since we use a list, which is a mutable object, this could lead to unexpected results.

@bnoordhuis Correct but if an empty list is actually passed, we ll still ignore it and create a new list, if we do additional or [] . We don't want that.
