It is comparable to [[Python (programming language)|Python]], [[Ruby programming language|Ruby]], [[Perl]] and many others. The language is semi-dynamic, and optionally [[strongly typed]], with full [[object orientation]]. All [[variable]]s in the language are first class objects. The design and implementation focuses on compactness and speed, using the [http://www.gnu.org/software/lightning/lightning.html GNU Lightning] [[Just-in-time compilation|Just In Time compiler]] (JIT). == Examples == # Ackermann if not (__arg__) # get input; println("Ackermann's function ...") println("Enter a number on the command line!") else NUM = Int(__arg__[0]) printf('Ack (3,%d): %d\n', NUM, Ack(3, NUM)) end if sub Ack(m, n) # one way if m == 0 return n + 1 elif n == 0 return Ack(m - 1, 1) else return Ack(m - 1, Ack(m, n - 1));; ;; # alternate way sub ackermann (m, n) return m ? (n ? ackermann (m - 1, ackermann (m, n - 1)) : ackermann (m - 1, 1)) : n + 1 ;; == See also == [[Queens|Queens New York]] A borough of New York City ==External links== * [http://www.qu-lang.org Qu Home Page] * [http://www.qu-lang.org/packages GTK, MySQL, curses, zlib modules for Qu] [[Category:Class-based programming languages]] [[nah:Qu]]
