  // Class Templates in platform code.
  //
  // Platform interface does not support templates directly.
  // This is a design decision. The purpose is to have type isolation
  // between platform library (or simply platform) and core library.
  // Another goal is to make a platform implementation a black box,
  // which does not leak implementation details in any form, be that types,
  // methods, or variables.
  //
  // Core library code does provide platform-specific class templates
  // on top of (a non-templated) platform support.
  //
  // For every common library template that needs platform support,
  // platform must provide an absl::any specialization of class template:
  template <typename T>
  static Ptr<AtomicReference<T>> createAtomicReference(T initial_value = T{});
