These are true, though I don't think 1) is that useful. More importantly,
they
3) are introspectable, so a RAD tool (such as Glade) can find out what
properties an object has, without special code for each widget.
4) don't mess with ABI. You can add a property without worrying about
changing the size of the struct. The new private instance data thing in glib
2.3 also does this, howeer.
