Subject: weak references
From: tyra3l@gmail.com (Ferenc Kovacs)

To spare the "5.4 features vote" thread from the off-topic discussion,
we can continue here.
Hannes Landeholm brought this idea up, see
http://news.php.net/php.internals/53956 and
http://news.php.net/php.internals/53959
I would suggest that Hannes create an rfc, and add some examples and
introduce the weak references in general and how this can be useful,
what problems do they solve (it was discussed in the bugreport, but it
wasn't clear as far as I can tell from the comments).
if I understand this right, Hannes proposed adding a new Spl
class(interface?), which can store and retrive a collection of
variables without incrementing the refcounts, so they can be freed if
they aren't used other than in this collection.

Hannes please correct me if I'm wrong somewhere.
