 I didn't plan this out in advance, so things are a bit more messy than I would like.
 
 * [Stacked Borrows: An Aliasing Model For Rust]({% post_url 2018-08-07-stacked-borrows %}) is the first post of the series and describes my initial ideas of what Stacked Borrows would look like before I started implementing them. It might be interesting for some of the context it gives, but is largely superseded by the next post.

-* [Stacked Borrows Implemented]({% post_url 2018-11-16-stacked-borrows-implementation %}) describes Stacked Borrows 1 and my experience implementing it. It is self-contained; I was not happy with some of my explanations in the original post so I decided to give it another shot. This is the best post to start with, if you are catching up.

 * [Barriers and Two-phase Borrows in Stacked Borrows]({% post_url 2018-12-26-stacked-borrows-barriers %}) describes how I extended Stacked Borrows 1 with partial support for two-phase borrows and explains the idea of "barriers". You do not have to have read that post to understand Stacked Borrows 2, except for the parts that specifically refer to barriers and two-phase borrows.
