Ruby

"Ruby is a dynamic, reflective, object-oriented, general-purpose programming language. It was designed and developed in the mid-1990s by Yukihiro "Matz" Matsumoto in Japan.  According to its authors, Ruby was influenced by Perl, Smalltalk, Eiffel, Ada, and Lisp.[13] It supports multiple programming paradigms, including functional, object-oriented, and imperative. It also has a dynamic type system and automatic memory management."http://en.wikipedia.org/wiki/Ruby_(programming_language)
