What I'm looking for is something that doesn't do any copying, but, rather, literally sets aside the variable and then restores it later.
Why did you post this as an update instead of replying to my node? I would have told you earlier that my solution does no copying. Please have a second look. If you still don't understand, let me know where you think copying is occuring.
