Those of you interested in this (automatic accessors, that is) in the
context of Cocoa might look into Key Value Coding:

call accessor and set functions.
For instance, you can have a String myStr property that actually sets
something in a dictionary in its implementation, like in Ondra's
example,
transparently. This lets the user do simply:
MyClass.myStr = "Blah"
String myLocalStr = MyClass.myStr;
And both will not set the variable directly but will instead call the
associated get or set function. Pretty neato, if you ask me ;)
Did you ever play with Dylan???
You would've really liked it's design as far as I can tell. As soon as
you
declared a member variable, it immediately had an accessor and setter
written for it. To make something private in Dylan you just overrode
it's
accessor and/or setter to do nothing/return null.
It's been a while since I studied the manuals so I may not be 100%
correct,
but it was pretty cool.
Cheers,
Dave
