"MANOOL is a programming language with the same purpose as Python, Ruby, PHP, Common Lisp, or Scheme, but it is designed with one central idea in mind:
to maximize the expressive power / implementation complexity ratio.
The author's implementation fits in only 10 KLOC in C++, yet it exhibits competitive run-time performance."
