+`ThreadLocal` has first-class support and can be used with any primitive `kotlinx.coroutines` provides.
 It has one key limitation: when thread-local is mutated, a new value is not propagated to the coroutine caller 
 (as context element cannot track all `ThreadLocal` object accesses) and updated value is lost on the next suspension.
 Use [withContext] to update the value of the thread-local in a coroutine, see [asContextElement] for more details.
