Of course Ruby has arrays and hashes, and they’re even notated in the same manner as Perl: [] and {}, respectively. Read up a bit on some other object-oriented languages such as C++ or Java and I think you’ll begin to see why the type of the referent is more important than than the exact type of the reference.

I think you may have read this with your humor/sarcasm module uninstalled…

To be used in “enterprises”, Ruby has following (major) chanllenges:

(1) performance/scalability/maintainability…of deployment
(2) support for overall lifecycle: test, continuous integration, deployment, etc.
(3) integration with legacy: messaging, legacy databases, etc.

Fortunately, there are (at least, potential) solutions for all of these challenges. For enterprises willing to take (a little bit) higher risk, Ruby/Rails is already usable.
