Perhaps it's possible to defer the copying until the write operation
actually, but I suspect the logic would be quite complicated. It's like
Jill trying into slip a new picture book under the hand of her little
brother start as he starts drawing.

But as I said, the use of reference usually denotes that changes will
occur. If you don't want variable separation to occur, then don't use
references.
