The `MinSequenceContainer` (used in tests for `<flat_map>` and `<flat_set>`) currently provides `begin()`, `end()`, `cbegin()` but no `cend()`.
[[container.reqmts]](https://eel.is/c++draft/container.requirements#container.reqmts-33) lists member function `cend` as one of container requirements, together with `begin()` and others.
