Which can be eliminated by having property.setter, especially in the form: @property def foo(self): ... @foo.setter def foo(self, value): ... @foo.deleter def foo(self): ... This even preserves Guido's "read-only + read-write" use case, and saves us a builtin.

Although it begs the question what happened to @foo.getter.

I'm only +0 on this -- I can't quite pinpoint what's wrong with it but it doesn't fell 100% right. Maybe I just need to sleep on it.
