I was going through the "miscellaneous nodes" section and found this one of many to be interesting. So... I thought I would do a little digging and sure enough, consistent with one of the many glories of Perl (there is a module for just about everything), I found one, on CPAN, that generates Fibonacci numbers and related things.
This is the CPAN documentation URL:
http://search.cpan.org/author/VIPUL/Math-Fibonacci-1.5/lib/Math/Fibonacci.pm
And here is a little chunk of code, (all of 5 lines), which generates a 10 number Fibonacci Series:

#!/usr/bin/perl -w
use strict;
use Math::Fibonacci qw(series);
my @fibonacci=series(10);
print "@fibonacci\n";
