Nice try, but what I wrote was what I intended to say:
http://docs.python.org/library/functions.html#property

For all I know I could have used property objects several times in modules :)

Hmm, it doesn't seem to me like it's much of a big deal, for it to
described as anything like a "GoldenRule" or to advise against its
overuse.
You use it when its appropriate and don't use it when you it's not,
like any other feature.
