    Ruby is the most flexible language out there, imposing no limitations on the developers, giving all the expressiveness possible. Or so we think. But there are languages pushing dynamic features and expressiveness far beyond what is possible in Ruby. Some are old, like Lisp and Smalltalk, some are just emerging, purely experimental languages, like Ioke or Newspeak. In this talk, we will take a look at some of these languages and what they can do that Ruby can't. What does it mean, to be homoiconic? How does a language without keywords work? Can I dispatch in more than one direction? And what is partial evaluation?
