RE: facet-oriented programming

Yes, facet-oriented make you write more code, not less. But this is the mininum cost we should pay for manage the changes.

The key point is not to write less code, but to write mininum code while keeping maxinum posibility to change our mind.

Approach the correct design is a progress. We always do something wrong and get new knowledges. After that, we change our mind.

If we prove a new design is wrong, we want rollback. But, the wrong thing maybe not happened recently, maybe after we did that we did something good in other facet, When this happened, rollback would be hard.

What I'm interested in is change of design. When we change the design of a module, some parts of several classes must change together, that just like a facet.

Design always changes, and if the new design not work, we want change back, if just part of it works, we want keep the good part. We need to manage the change, as smooth as posible, 

In the view of managing change, all programs are facet-oriented.
