Based on the discussion, I think I'd go with defaultproperty. Great.

Questions: - Should this be in builtins, alongside property, or in a library module? (Oleg suggested propertytools.) - Do we need a short PEP? I think so. From the responses I'd say there's at most lukewarm interest (including from me).

Hm, I saw several responses from people who'd built something quite similar. This suggests to me that this is a common need.

You might also want to drop it and just add it to your personal (or Zope's) library.

I have something like this in Zope's library. I end up with a very small package that isn't logically part of other packages, but that is a dependency of lots of packages. I don't like that, but I guess I should get over it.

I must say that I am of 2 minds about things like this. On the one hand, I'd like Python's standard library to be small with packaging systems to provide "extra batteries". OTOH, I often find small tools like this that would be nice to have readily available.
