This post is about an aspect of the [RustBelt paper]({{ site.baseurl }}{% post_url 2017-07-08-rustbelt %}).
And then there is the question: Why exactly two modes? Would it be worth having more?
I honestly don't know, but I had to think of this a while back when I read [this post by glaebhoerl](https://internals.rust-lang.org/t/impl-t-clone-for-cell-rc-t/5397), the first part of which I would translate as "`Cell` could be considered a mode".

I'd also be interested in feedback on how understandable this post is; this is my first attempt at translating research results into a blog post.
