Coming from this question, named variadic arguments: http://www.digitalmars.com/webnews/newsgroups.php?art_group=digitalmars.D.learn&article_id=18586 It's a possible way to implement something like this Python code: def foo(x, y, **kwds): # here kwds is a dict of str:value With another kind of typesafe variadic function: void foo(int x, int y, Box[string] kwds ...) {} foo(1, 2, z:10, w:30); ==> In foo kwds == ["z":box(10), "w":box(30)]; (Variant or something else can be used instead of Box.)

While that can be useful, so far I've never find an use of "typesafe variadic functions for class objects" (See D docs about typesafe variadic functions). If no one uses this feature then it can be removed from D2.
