Bottled Gin:
Given a class object, is there a way to find out the number of
references to it. I have a situation where a container is
holding an object and I would like to remove the object from
the container if there is nobody else referencing it.
Is it possible in D?
What you want is a container that keeps weak references
(http://en.wikipedia.org/wiki/Weak_reference ).
Currently (I think) there are no weak references in Phobos, but
eventually it should be added. Probably somewhere there is some
implementation.
