For example in GUI code widgets reference each other all over the place. 
Cyclic dependencies are the reason that Rust has no GUI even like 
dlangui despite Rust community has much more resources. So I totally 
agree to IGotD: "People who ask for required ownership often don't know 
what they are asking for."
