Well, Ruby & Python are just like islam & Judaism or vim & Emacs.
They're very similar, yet distinct, and once you've chosen one path, it's hard to take another.
I'm really good at using Ruby, know the inner workings, wrote many plug-ins and applications, and contributed to the project.
There are many cool projects for Python that I'd love to understand, use and contribute to.
I tried some tutorials for Python, but it feels like a waste of time when I already know a OO high-level scripting language.
A common compiler would be really cool, but I don't know if it is even possible.
