Ruby is an annoying language in the sense that it feels like it does everything differently from every other language for the sake of it.
It's also infamous for being slow and resource intensive.
Back in the day, it was the language to pick to be "hip" and "modern". Nowadays? I don't see any reason to use it.
@olives As far as classical high level languages go I like it more than most partly due to the freedom it allows.
That said it has horrible handling of immutability. Sadly many languages handle that poorly.
