That said, there is no way right now to create two FamixReferences to represent the same entity in code, but does it make sense?
Did not understand ... ?
2 references representing the same entity? A reference is not an entity?
As for Alex question, I would agree with Simon: It might be usefull to know that a method makes 1 or 10 different references to the same other entity. I believe verveineJ does it that way (I didn't check).
