Ruby is a modern, dynamic, post object-oriented/functional programming language. It blends syntax and features from Perl, Lisp, Eiffel, Ada and Smalltalk, with flexible expressions, dynamic but strict typing, mixins and explicit scoping. It's available in different runtimes, on most platforms, and a complete extension ecosystem.
