    * In particular, it cannot encapsulate the predefined registry keys
    *   such as HKEY_CLASSES_ROOT.
    * These classes are considered "always open",
    *   and the destructor should not close them.
    * Rather than trying to detect these predefined keys,
    *   we simply don't allow them to be constructed.
    * In practice, this is a limitation without much consequence.
    * If this were a library designed for standalone use,
    *   this limitation might not be appropriate, but it's fine here.
