The other thing to remember is that because the 'registry' contains
references to the instances, they won't be garbage collected.
Is there any other way out in this case?
I have factory methods - and I have to loop over them - sort of Chain
of Responsibility pattern.
Having a registry inside the class instance and looping through them
was the only clean thing I could think of.
I understand that garbage collection would be an issue - but is there
any way out?
You may keep all that structures - just use weak references (see the
weakref module).
There isn't a WeakList nor WeakSet out-of-the-box but you may use a
WeakKeyDictionary (set the value to anything, None by example).
