No, I spoke correctly.  The namespace reserved for the implementation is
all double underscores, and all single underscore followed by a capital.
 Single underscore followed by a lower case is NOT reserved for the
implementation, and is therefore free for use by the user, and therefore
the implementation must not interfere with the user's use of that namespace.
