Pony relates to Rust in terms of what they are trying to 
accomplish with ownership. Pony's iso reference capability seems 
to mirror Rust's borrow checker rule that you can only have one 
mutable reference. D's DIP 1000 already seems to incorporate one 
of the borrow checker's rules on scope length. Adding something 
like iso would probably help in the ownership department after 
DIP 1000 is officially added.
