The rule is that "mutable references contained within a mutable static may be referenced in the final value of a constant." However, the key here is that "mutable static" means either a `static mut` item or a `static` item with an interior mutable type. We had made that clear over in `const-eval.const-expr.path-static` but not in our rules about const item validity, and our link for "mutable static" had implied it may mean `static mut`. Let's fix that and add an example to demonstrate the point.
These link reference definitions were used in `const.no-mut-refs` and are no longer needed.

I had a WIP commit to clean up the language we're about to delete. If the commit looks OK to you, I'd like to put this in the history for posterity's stake. I've stacked your commit onto it and also deleted the link reference definitions that are now unused. |
