Amanieu opened PR #2714 from more_entitylist to main:

This PR contains several improvements to EntityList:

• swap_remove had poor codegen because it ends up calling remove and doing a bunch of redundant work. I factored out the code to remove the last element of a list into remove_last, which is used by both remove and swap_remove.
• Added deep_clone which copies all elements to a new list. This is difficult to implement efficiently otherwise since it requires mutable access to the list pool for one lists while reading from another list.
• Added truncate which efficiently shortens a list without needing to remove elements individually.
