I am confused here. What [ReturnsModifiedPointer] has to do with copying/referencing an object?
With GLib.SList list = given_list; you do not create a copy of an object but owned reference/pointer. And if you do anything to that reference, you will modify given_list too. And in most cases not copying object, but referencing it is desired behaviour, so I don't see problem here. I would also not desire assuming that copy should be created whenever I assign object from unowned reference to owned reference. I think that everything is ok here, unless I am missing something. Could you describe the result you expect from the code you provided?
