Maple has a bunch on internal utils that could be useful outside of logging. For example, you can convert a statement lambda into a list of Names/Values via the MapleSpi factory. E.g.
>> // save this meta instance somewhere
>> var metaIInstance = MapleSpi.instance().generate(Schema.class);
>> // convert a statement into names/values
>> var instance = metaInstance.newSchemaInstance();
>> s.handle(instance);
>> var namesValues = metaIInstance.toNamesValues(instance);
