There was a problem hiding this comment.
(Currently reading through PR #146992 commit by commit to catch up.)
Quick side note: ElementStackClassStack is not actually a stack, it's a tree!
Reading through this for the first time that's a bit confusing (moreso the resulting method names like (was renamed in a later commit)).enter_stack don't help me form an intuition (granted, it's 2AM for me rn and I'm only skimming the code)

Nah, it used to be a tree, it's now a stack (always one child). :3

…on, r=yotamofek Fix invalid tag closing when leaving expansion "original code" Fixes rust-lang#148184. Problem was that in case an element inside the expansion's "original" element was not closed, this element would get its `pending_exit` field set to `true`, removing it when the next non-mergeable item gets pushed instead of being put inside it, and then next `exit_elem` would try to exit an empty class queue. r? `@notriddle`

Fixes #148184.
Problem was that in case an element inside the expansion's "original" element was not closed, this element would get its
pending_exitfield set totrue, removing it when the next non-mergeable item gets pushed instead of being put inside it, and then nextexit_elemwould try to exit an empty class queue.r? @notriddle
