Isolated by example

[Dylan Knutson via Digitalmars-d]

Correct me if I'm wrong here, but this seems really similar to 
how Rust does owned pointers and move semantics. Or is there a 
large conceptual difference between the two that I'm missing?

I believe that the issues that people are bringing up with bad 
interaction with UFCS, and losing isolated data after passing it 
to a function, are managed in Rust with the notion of a borrowed 
pointers. Perhaps something analogous to this could accompany the 
`isolated` idea?
