> 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.
