19Perl history in brief, by Larry Wall:

GS
21 Perl 0 introduced Perl to my officemates.
22 Perl 1 introduced Perl to the world, and changed /\(...\|...\)/ to
d516a115 23 /(...|...)/. \(Dan Faigin still hasn't forgiven me. :-\)

24 Perl 2 introduced Henry Spencer's regular expression package.
25 Perl 3 introduced the ability to handle binary data (embedded nulls).
26 Perl 4 introduced the first Camel book. Really. We mostly just
d516a115 27 switched version numbers so the book could refer to 4.000.
cac726e9 28 Perl 5 introduced everything else, including the ability to
d516a115 29 introduce everything else.

36=head2 PUMPKIN?
37
38[from Porting/pumpkin.pod in the Perl source code distribution]
39
40Chip Salzenberg gets credit for that, with a nod to his cow orker,
41David Croy. We had passed around various names (baton, token, hot
42potato) but none caught on. Then, Chip asked:
43
44[begin quote]
45
46 Who has the patch pumpkin?
47
48To explain: David Croy once told me once that at a previous job,
49there was one tape drive and multiple systems that used it for backups.
50But instead of some high-tech exclusion software, they used a low-tech
51method to prevent multiple simultaneous backups: a stuffed pumpkin.
52No one was allowed to make backups unless they had the "backup pumpkin".
53
54[end quote]
55
56The name has stuck. The holder of the pumpkin is sometimes called
57the pumpking or the pumpkineer.
