Ruby is the Best Javascript
summary
Claims Ruby can be made to look and behave like JavaScript by abusing syntax and metaprogramming: defines Javascript-style var and console.log, builds anonymous functions that are declared like JS and invoked like methods, and runs the demo code successfully. Techniques include global method_missing, using Object.new and instance_eval to bind block args, and using eval + local_variables search plus send and define_method. Six core stdlib receivers (to_a to_int etc) break with the hack, and the contraption actually works onstage.
