Footnote:  

Although I think Scott did an admirable job of showing how the property
function could be served with the new decorator syntax, I don't think the
trade off in convenience is necessarily worth the convoluted helper
functions that make this short-cut doable.

That being said, I'm quite pleased that Scott spelled it out, and I have in
fact used his invention (in subsequent code).  

In yet more recent code (satacad.py with Vector, Edge and Polyhedron
classes), I'm back to straight attr = property(args) syntax, and quite
satisfied with it.  I feel no strong temptation to use decorators in this
context.

In sum, I wouldn't necessarily go "the whole nine yards" as you've put it.
