**Abstract**\\
I describe an experimental object-oriented programming system, ASL2, that supports program development by means of a series of abstraction steps.  The system allows immediate object construction, and it is possible to use the constructed objects for concrete problem solving tasks.  Via a number of gradual abstraction steps the objects are derived and transformed to a conventional object-oriented source programs.  I introduce two levels of object classification, weak and strong object classification.  Strong object classification relies on conventional classes, whereas weak object classification is looser, and less restrictive.  As a central mechanism, weakly classified objects are allowed to borrow methods from each other.  ASL2 supports class generalization, as a counterpart to specialization and inheritance in mainstream object-oriented programming languages.  The final abstraction step discussed in the paper is a syntactical abstraction step that derives a source file with a syntactical class form.
