 Since last fall, [Neven](https://perso.crans.org/vanille/) has been doing an internship to develop a new aliasing model for Rust: Tree Borrows.
 Hang on a second, I hear you say -- doesn't Rust already have an aliasing model?
 Isn't there this "Stacked Borrows" that Ralf keeps talking about?

-Indeed there is, but Stacked Borrows is just one proposal for a possible aliasing model -- and it [has its problems](https://github.com/rust-lang/unsafe-code-guidelines/issues?q=is%3Aopen+is%3Aissue+label%3AA-stacked-borrows).

 The purpose of Tree Borrows is to take the lessons learned from Stacked Borrows to build a new model with fewer issues, and to take some different design decisions such that we get an idea of some of the trade-offs and fine-tuning we might do with these models before deciding on the official model for Rust.
 
 Neven has written a detailed introduction to Tree Borrows [on his blog](https://perso.crans.org/vanille/treebor/), which you should go read first.
