. The main
purpose of this is to provide a representation that does not have a reference to the key. This is useful in
situations where the key is already known or stored elsewhere, making serialization and deserialization more
efficient.
Note that this should not be used to optimize memory overhead, since the saving of an additional reference to a
key (a single object reference) does not warrant the cost of constructing an InternalCacheValue. This only
makes sense when marshalling is involved, since the cost of marshalling the key again can be sidestepped using an
InternalCacheValue if the key is already known/marshalled.
