          Ruby is a language designed in the following steps:
          * take a simple lisp language (like one prior to CL).
          * remove macros, s-expression.
          * add simple object system (much simpler than CLOS).
          * add blocks, inspired by higher order functions.
          * add methods found in Smalltalk.
          * add functionality found in Perl (in OO way).
          So, Ruby was a Lisp originally, in theory.
          Let's call it MatzLisp from now on. ;-)
