What do you mean? Not the D I played with?

void test1(T...)(T ts) {
     writeln(ts); //works as expected
}
void test2(string s, T...)(T ts) {
     writeln(s);  // requires manual specifying of each type
     writeln(ts); // e.g. test2!("foo", int, int)(1,2)
}
void test3(string s, T...)(T ts...) {
     writeln(s);  // silently dies when called with
     writeln(ts); // test3!("foo")(1,2,3,4) in v2.034
}
