I noticed there's now a Delete() function, but does it actually delete it fully?

In past games, you'd have to do Disable and then MarkForDelete to make sure it's completely removed, but then there's this.

Does it work the same as MarkForDelete, except not needing the object to be disabled?

Any insight would be appreciated.

http://www.creationkit.com/Delete_-_ObjectReference is the Papyrus version of MarkForDelete. It'll only work, however, for [FF] range forms like stuff created via http://www.creationkit.com/ObjectReference.PlaceAtMe_(Papyrus).
