I think this is ready now. I'll just need to add an overview for the code and remove the old tests (the new ones should cover all those cases now).

#13200 still needs to be looked at as well.

@llogiq Any chance you'll finish the review before Thursday? That's the last sync to get this in for 1.83.

The most pressing of the issues are now fixed in #13290.

[llogiq]

Sorry it took so long to review, but this seems good to merge. Let's hope we're in time.

🔒 Merge conflict

This pull request and the master branch diverged in a way that cannot be automatically merged. Please rebase on top of the latest master branch, and let the reviewer approve again.

How do I rebase?

Assuming self is your fork and upstream is this repository, you can resolve the conflict following these steps:

1. git checkout non_copy_const_ice (switch to your branch)
2. git fetch upstream master (retrieve the latest master)
3. git rebase upstream/master -p (rebase on top of it)
4. Follow the on-screen instruction to resolve conflicts (check git status if you got lost).
5. git push self non_copy_const_ice --force-with-lease (update this PR)

You may also read Git Rebasing to Resolve Conflicts by Drew Blessing for a short tutorial.

Please avoid the "Resolve conflicts" button on GitHub. It uses git merge instead of git rebase which makes the PR commit history more difficult to read.

Sometimes step 4 will complete without asking for resolution. This is usually due to difference between how Cargo.lock conflict is handled during merge and rebase. This is normal, and you should still perform step 5 to update this PR.
