Avoiding unbreakable reference cycle with value types and closures?

The main problem is that after creating this reference cycle there's no way to deallocate it at all

Ah true. So you'd have a memory leak of basically one value clutching at itself
My personal impulse is that I want to be able to declare weak closure references, since closures are reference types anyway, but I'm sure there's a technical reason for why weak closures are not possible...
