cachedparameter can be annotated with
exclusive. The DSL will indicate sharing opportunities to the user by showing a warning.
Shared caches with reference types must never return
null for their initializer
when they are used in guards, because the
null value is reserved for the
uninitialized state. An
AssertionError will be thrown at runtime if that is the case.
Shared caches with primitive types must not be used at all in guards.
