* Annotation that indicates an inner class has a weak relationship to its owning class.

* Lambdas can be given a weak outer reference by declaring a local variable with this annotation
* and assigning the lambda expression directly to the local variable. WeakOuter is only allowed on
* local variables, not fields, to encourage the annotation to be used where the lambda is declared.
