Perl *one-liners* are often terse and cryptic. Perl programs generally vary a lot in terms of how terse and cryptic they might be depending on who wrote them.
By the way, I wonder what versions of the program he has used. Some of the Perl programs (such as lists.pl) have rather a lot of comments in them, for instance. Have these been removed before counting code size?

I thought the interesting thing was that traditionally, Perl programs are very terse and cryptic. Pike programs are in my view a lot more readable, so you'd think they would also be larger.
