Yes, that's where my thoughts incepted. When I noticed it, I wondered
whether a new type is the best solution for lazy initialization of final
values (and still believe a Supplier.cache(Supplier<T> computer) would be a
nice addition). But your answer about the scope of StableValue being
broader than just lazy initialization makes my comment not so relevant.
