It would be nice to recommend avoiding using "global" state in the libraries, that later is almost impossible to test and/or mock.
We tend to favor explicitly spelled-out APIs for the such state: datetime's Clock.System.now(), Okio's FileSystem.DEFAULT.read* as opposed to top-level now(), read(path) etc. (the most notable existing API that falls into this trap is coroutine's Dispatchers.Default)
