Perl history in brief, by Larry Wall:
.PP
.Vb 9
\&    Perl 0 introduced Perl to my officemates.
\&    Perl 1 introduced Perl to the world, and changed /\e(...\e|...\e)/ to
\&        /(...|...)/.  \e(Dan Faigin still hasn\*(Aqt forgiven me. :\-\e)
\&    Perl 2 introduced Henry Spencer\*(Aqs regular expression package.
\&    Perl 3 introduced the ability to handle binary data (embedded nulls).
\&    Perl 4 introduced the first Camel book.  Really.  We mostly just
\&        switched version numbers so the book could refer to 4.000.
\&    Perl 5 introduced everything else, including the ability to
\&        introduce everything else.

[from Porting/pumpkin.pod in the Perl source code distribution]
.PP
Chip Salzenberg gets credit for that, with a nod to his cow orker,
David Croy.  We had passed around various names (baton, token, hot
potato) but none caught on.  Then, Chip asked:
.PP
[begin quote]
.PP
.Vb 1
\&   Who has the patch pumpkin?
.Ve
.PP
To explain:  David Croy once told me once that at a previous job,
there was one tape drive and multiple systems that used it for backups.
But instead of some high-tech exclusion software, they used a low-tech
method to prevent multiple simultaneous backups: a stuffed pumpkin.
No one was allowed to make backups unless they had the \*(L"backup pumpkin\*(R".
.PP
[end quote]
.PP
The name has stuck.  The holder of the pumpkin is sometimes called
the pumpking (keeping the source afloat?) or the pumpkineer (pulling
the strings?).
