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

    yes a bit from the original post: in fact:
    perl -E "say$x*=$_ for++$x..3,0,1,-1" 1 2 6 0 # must be 1 0 # too 0 # must be undef or Error
