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` [download]	[reply] [d/l]

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` [download] L 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.	[reply] [d/l]

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` [download] L* There are no rules, there are no thumbs..
