By the way, this also applies for the docs -- we will eventually use
upstream's, and thus it is best to try to match the docs too.

It also means we probably want to put this into `std_vendor.rs` if we
are going to copy-paste the docs verbatim, even if it is not code as
such (no implementation upstream since it is a built-in).

E.g. for a similar case, please see:
