Delete Duplicate and original objects

[hythamthelove]

Hello, we all know about the overkill command which deletes only the duplicate object, but i want a lisp routine which find the duplicates and deletes the duplicate and the original object. The objects i am talking about are usually Line, Mtext and spline and the original and duplicate objects will have the same colour the same layer the same everything no worries for that.

Thank you in advance
