I'm sure Greg has in mind this thread (which was in fact also the
thread that floated the idea of getting rid of __del__ in P3K):
http://mail.python.org/pipermail/python-dev/2004-November/049744.html
As that said, some weakref gc semantics are pretty arbitrary now, and
it gave two patches that implemented distinct semantic variants. A
problem is that the variant semantics also seem pretty arbitrary ;-),
and there's a dearth of compelling use cases to guide a decision. If
someone devoted enough time to seriously trying to get rid of __del__,
I suspect compelling use cases would arise. I never use __del__
anyway, so my motivation to spend time on it is hard to detect.
