*sighs* How suitable is Perl for high-end apps? Let's see ...

• Amazon runs on Perl. (Mason, to be specific.) It's that "Enterprise" enough?
• Perl runs the investment banking applications for BankOne. All of them. (Well, the ones that don't break on a daily basis ... guess what those are written in.)
• Among the investment house in NY, EVERY single one of them has millions invested in Perl/Sybase applications. Don't believe me? Ask mpeppler.
• MasterCard has a Perl application that is used to generate around 100 million dollars in business (and growing). The group tried to rewrite the app in Java. Two years later and all the Java developers are helping out on the Perl app.
• Motorola uses Perl to simulate a telecom switch when testing new software for the base stations. (That's the other side of the 2-way radio link with your cellphone.) Over one million tests per day, all reported and statistically analyzed. This product was used to help search for cell signals within 48 hours of 9/11.

http://www.perl.com/ also has a bunch of success stories.
