I'd vote against this. It looks to me like a great way to confuse users 
and complicate interfaces. I'd rather go towards transparency.
Generally I'd not mutate arguments, only the receiver. If there's a 
valid case to mutate an argument, it should be documented and evident. 
The user then has to provide a duplicate if he still needs the original.

Just my 0.02���
