Message OO

==========

This package gives you the great opportunity of real object-oriented

programming.

For example, you may write

    (use-package :message-oo)

    

    (defmessage list (:add item) (append list (list item)))

    (defmessage list (:map func) (mapcar func list))

    (defmessage list (:reduce func) (reduce func list))

    (defmessage number (:+ number2 &rest numbers) 

       (apply '+ number number2 numbers))

    (@ nil

       (:add 1)

       (:add 2)

       (:add 3)

       (:map (@ '(:+ 3) :fn))

       (reduce #'+)) => 15

You may think of last command as nil.add(1).add(2).add(3).map(..).reduce(...)

Every next step is applied to the result of previous as in UNIX shell pipeline.

Enjoy!
