Thank you for your replies. But they don't deal with my original
question. :) I have read the thousands of posts all saying "self is
good" and they are right. But this time I want to be different m-kay?
I figure that there might be some way to solve my problem by doing
this:

The more features a language has, the harder it becomes to learn. An
example of that is C++ which has almost everything. Classes, structs,
templates, strange keywords that noone uses like auto, inline const,
passing by reference/value, enum, union, lots of macros, multiple
inheritance, namespaces e
x. But the selfless code has
problems with that. I want it to work exactly like how the situation
is handled in Java and C++.
