What I also don't like about the current situation is that every
correction to the mechanism of this classes has to be applied to both
separately. But I think we should be a bit more careful here than just
replace one by the other. We still want to be able to use GNUstep GUI
with other foundation libraries than base, although currently nobody
uses any of these combinations. When a class in GUI (NSTextStorage) is
directly dependent on a class in base (GSMutableAttributedString) we
cannot easily replace this.
