Hi,

Ferenc: Good idea to move the discussion to a separate thread.

Etienne: Awesome. I wish I had time to write the patch myself. I could
probably put some hours into adding more details to the RFC though.

The only problem as I see it by making it a weak reference class instead of
a weak reference collection is that you would end up with a bunch of
unnecessary indexes in the array that points to invalid references. The
simplest solution to this problem if you still want to implement it as you
have begun to is to allow catching the cleanup event in a callback so you
can manually unset the index. Should I add these concerns to the RFC?

Thanks a bunch,

Hannes
