What’s not solved with weak refs?

[ben-schaaf]

What's not solved with manual memory management? The point is not that you can't solve it, the point is that reference counting isn't the whole solution for garbage collection unlike a tracing gc for instance.

Weak reference counting is still reference counting.

[giornogiovanna]

It can always be solved with weak references.
