In D2 there are even typesafe Variadic Functions for dynamic arrays and class objects:
http://www.digitalmars.com/d/2.0/function.html

An example:

class Foo {
    int x;
    string s;

    this(int x_, string s_) {
        this.x = x_;
        this.s = s_;
    }
}

void test1(int[] array ...) {}
void test2(int x, Foo f ...) {}

void main() {
    test1(4, 5, 6);
    test2(1, 4, "text");
}


So far typesafe variadic functions for class objects is an useless feature for me.

Once named arguments are present, typesafe variadic functions for associative arrays may look like:

void test3a(int[string] aa ...) {}
void test3b(Variant[string] aa ...) {}

You may call them like this:
test3a(x: 1, y: 2, good: 3);
test3b(x: 1, y: 2, good: "right");
