They were resolved with modern hygiene, making this just a strange way to shadow lifetimes.
Declarations were already modernized, resulting in cases where a macro couldn't resolve it's own identifier.

There was a problem hiding this comment.
Why is this changed, and why did it work previously?
I don't quite remember all the differences between many kinds of ribs that act as "barriers" for names.

There was a problem hiding this comment.
So the reason that this has little effect is that there is already an AssocItemRib around all associated items that holds any generic parameters. Since generic parameters can be seen through associated items, this rib isn't stopping any names from being visible.
The reason for the change is so that function parameters don't end up in an associated item rib, and get resolved with the wrong hygiene.
