So what are you saying, that people who aren't adult enough
should be given a tool that's nice and easy but leads them
to write buggy code? That doesn't seem like a responsible
thing to do.

I don't see why it needs to be anywhere near that complicated.
All use of weakrefs can be hidden behind a call such as

   register_finalizer(self, func, *args, **kwds)

and we just need to say that func should be a plain function,
not a bound method of self, and self shouldn't appear anywhere
in the arguments.

Anyone who's not intelligent enough to understand and follow
those guidelines is not intelligent enough to avoid the
pitfalls of using __del__ either, IMO.
