Yes, but that is no guarantee at all, as all my CGI's in 5.10 were newer than that. As I just posted on p5p, here's some more info.

For CGI 3.38, the shortest version would be:

CGI has the longest pod from the core .pm's, so getting a success is relatively easy. It also happens to be the *only* CORE .pm that contains these four words. I found no other modules (even none-CORE) that enable this short version.

Close come:

• POE (1.003)
  perl -lap -0e'BEGIN{close STDIN;require POE}$F[2821]=substr$F[2821],-12,6;$_="@F[610,865,2455,2821]"'
• XML::Twig 3.32
  perl -lap -0e'BEGIN{close STDIN;require XML::Twig}chop($_="\L@F[653,11676,5,19071]")'
• Text::CSV_XS 0.52 (with a bit extra obfuscation)
  perl -lap -0e'BEGIN{close STDIN;require Text::CSV_XS}$F[$#F/6-$=]=~s/=b/h/;$_="@F[257,679,435,791]er"'
