> This need was discussed on the mailing list [1] and will be obviated by code generation for POJO serializers and comparators [2] (as I understand, i.e., {{LongValue}} will now simply be treated as a POJO which happens to contain a {{long}} and a specialized serializer and comparator will be generated).
> In the meantime, and since {{ValueTypeInfo}} will need to be reworked to use the new generators, I think it is worthwhile to add specialized serializers and comparators for the {{CopyableValue}} types.
> This will also provide another point of comparison for the performance of the generated serializers and comparators.
