 Review comment:
   yeah -- that was an over-generalization.   I agree that if the object is 
large that's a concern, but in these cases it's not.

 Review comment:
   these shouldn't be pointer receivers -- only methods that modify the content 
should be,  e.g. SetID()..:
   ```
   func (parameter TOParameter) GetID() ...
   ```
