if you want a more general way to create anonymous functions in Perl 6, it's not that many more keystrokes away: sub ($a, $b) { $a + $b, [1, 2, 3], [4, 5, 6] } Or even sub { $^a + $^b, [1, 2, 3], [4, 5, 6] } So yes, the whatever-star isn't the most powerful thing imaginable, but it's good enough for very simple cases, and more powerful mechanism are available too.
