This Raku module is a dependency of JSON::Marshal and JSON::Unmarshal in order to save duplication, it is intended to store a separate JSON name for an attribute where the name of the JSON attribute might be changed, either for aesthetic reasons or the name is not a valid Raku identifier. It will of course also be needed in classes that are going to use JSON::Marshal or JSON::Unmarshal for serialisation/de-serialisation.

Of course it could be used in other modules for a similar purpose.
