I'm not familiar with Nim. Does it also support weak references?

A significant portion of the problems with cycles in ARC are parent references.

Weak references are possible with the .cursor pragma applied on local variables and object fields. This release introduces cursor inference too, enabled by default with --gc:arc|orc, but only for local variables.
