(Just thinking out loud...)

Maybe we should create an alternate "object-oriented" version of pystone as a way to inject more attribute access into a convenient benchmark. Even if it's completely artificial and has no connection to other versions of the Drhystone benchmark, it might be useful for testing improvements to attribute access.
