sub my_factorial { ... if($n == 0) { $r=0; } return $r; }
Your function says that 0 factorial is 0. But it's not; it's 1.

    Perl 6 is very generous in this:

    pugs> sub postfix:<!> (Int $n) { [*] 1..$n } undef pugs> say $_! for ^10 1 1 2 6 24 120 720 5040 40320 362880 undef

    (I personally believe that I've posted this before here and in different media, but that's jut because it's quite about the only thing I can actually do in pugs ATM.)
