Almost impossible in case of the AWT. I once (with biss-only) had the ambition
to divide the whole AWT stuff into layers, with clean dependencies among them.
But it doesn't work even if you go to great lengths in the implementation,
since the circular ref is already in the interface (e.g. Component.getParent()
-> Container, Container extends Component, java.awt.event <-> java.awt,..). I
had to use a lot of runtime constructs in biss-only to keep this at a minimum,
which I consider as *bad* (increasing structure complexity and runtime costs for
pleasing the compiler). And even with this, I had to use dummy "forward"
classes of higher layers in the lower ones - which makes the whole build
process more eror-prone and complex instead of simplifying it. Was a good goal
without a good way to reach it <sigh>
