olin means love
the etymon of which is 'volim' in Croatian
this is object oriented programming implemented by one scheme function called 'CLASS'
class is function
object is function
message is symbol
to create a class
by an associate list of messages and methods
(define <class-name>
(CLASS
(cons <message> <method>)
(cons <message> <method>)
...))the shape of method is
(lambda (this <message> <argument> ...)
<body>)to create an object by an associate list of messages and methods
this associate list of object
is appended to the associate list of the class
(<class>
(cons <message> <method>)
(cons <message> <method>)
...)right before the creation
the massage `require is passed to the object
which should returns a list of messages
which must occur in the associate list of object
right after the creation
the massage `init is passed to the object
message passing is like
(<object> <message> <argument> ...)when passing a message to a object
if the associated method is not a function
it is returned
if the associated method is a function
it is called
[note that object is function
I have to put an object into a box to *not* call it]
to update a method with new value
(<object> (up <message> <new-value>))can not inherit
