@@ -178,6 +179,6 @@ For unsafe code authors, the slogan summarizing this post is:
 I think we have enough experience writing unsafe code at this point that we can reasonably discuss which validity invariants make sense and which do not -- and I think that it is high time that we do so, because many unsafe code authors are wondering about these exact things all the time.
 
 The plan is to open issues in the [UCG RFCs repo](https://github.com/rust-rfcs/unsafe-code-guidelines/) soon-ish, one issue for each type family that we need to make decisions on wrt. validity.
