So you have basically two solutions. If your variable is an instance variable, you can declare that your class is weak and initialize it with a size of 1, the fixed fields will remain strong, only the indexed field will be weak. You can have a look at WeakKeyAssociation and WeakValueAssociation for examples. Otherwise, you can wrap your variable into a weak array of size 1. Later slots will be able to do the job transparently. > Uko
