That paper says:
> Note for editor: All the functions in [algorithms.general] must be marked with constexpr, except functions shuffle, sample, stable_sort, stable_partition, inplace_merge, functions accepting ExecutionPolicy and algorithms that have ValueSwappable requirement(22.214.171.124):
`std::rotate` is not one of the updated functions in that paper. It is updated in the standard, though. <http://eel.is/c++draft/alg.rotate>
We have only done a very few of them. I am starting to make my way through the list. There are several papers which update various algorithms IIRC.
