It seems to have some interesting features, though i don't know much about it.
I like how you can pass in function parameters by name as in SQL, i always though that was something every language should support. I like how everything is an object as well.
I'm not a fan of the syntax nor the verbiage (why begin/rescue instead of try/catch?).
It's not a language that i see myself picking over another unless it becomes so popular i have to start using it.
