Just yesterday Pankaj and I were talking about how everything that one can think of is most definitely available on CPAN. And I jokingly told that maybe, just for the heck of it, we should write a skeletal Google::Finance, and once it eventually launches we’ll probably just need to make some changes to the fetch structure or something. (How difficult can it be, hey?)
Anyway, Google Finance has launched. Maybe someone will put up a module on CPAN soon—not us; it’s too boring.
