trait ScopedRef[A]

A ScopedRef is a reference whose value is associated with resources, which must be released properly. You can both get the current value of any ScopedRef, as well as set it to a new value (which may require new resources). The reference itself takes care of properly releasing resources for the old value whenever a new value is obtained.
