There was a problem hiding this comment.
is_temp would be slightly clearer I think; return false inside this function is a double negation which is somewhat confusing.

You are right, I will change this function in the next update of derefer.

Pull Derefer before ElaborateDrops _Follow up work to rust-lang#97025 rust-lang#96549 rust-lang#96116 rust-lang#95887 #95649_ This moves `Derefer` before `ElaborateDrops` and creates a new `Rvalue` called `VirtualRef` that allows us to bypass many constraints for `DerefTemp`. r? `@oli-obk`
