Allow data structures to be extended or decorated

RPG currently allows us to define a data structure with the same layout another with the LIKEDS keyword.

It would be useful to be able to use a similar keyword to define the basic structure, but also to extend the data structure and add additional subfields to the end.

This would allow developers to have a base type that defines an archetype - e.g. a person that is then extended by other specialisations which have additional properties specific to them - e.g. employee, manager, customer..

In the examples below I have used 'extends' as the keyword. 

dcl-ds person_t qualified template;
  firstName char(30);
  surname   char(30);
  dob       date;
  address   likeDs(address_t)
end-ds; 

// The employee_t data structure is a specialisation of the person_t structure, adding some extra fields.
dcl-ds employee_t extends(person_t) template;
  employeeNumber int(10);
  departmentCode char(2);
end-ds;

// The employee_t data structure can itself be extended:
dcl-ds manager_t extends(employee_t) template;
  authorisationLimit packed(15:2);
end-ds;

// The customer_t data structure is another specialisation of person_t, adding some other extra fields
dcl-ds customer_t extends(person_t) template;
  customerNumber   int(10);
  emailAddress     char(128);
  registrationDate date;
end-ds;
