    Easy to make it 30 with
    $a=1;print$a*=$b+=1,$/for a..k

        Though we may have strayed a bit from the original golf, yours can be whittled by three strokes:

        > perl -E "$a=1;say$a*=++$}for a..k" > perl -E "say$x*=$_ for++$x..11" 1 2 6 24 120 720 5040 40320 362880 3628800 39916800

        also this solution works only for series of consecutive integers starting with 1
        perl -E "$a=1;say$a*=++$}for @ARGV" 0 1 2 3 1 2 6 24 perl -E "$a=1;say$a*=++$}for @ARGV" 1 3 1 2

        There are no rules, there are no thumbs..
        Reinvent the wheel, then learn The Wheel; may be one day you reinvent one of THE WHEELS.
