Crystal comes from a Ruby background, but it's far more than compiled Ruby. As a general purpose language mainly aiming at application development it can surely compete with any of the above in that field. The main objective inherited from Ruby is the focus on developer hapiness. While doing that it doesn't back down on performance or interoparability.
