CLASS - Alias for __PACKAGE__

       From February 2022 onward: Jacques Deguest <jack@deguest.jp>

       CLASS and $CLASS are both synonyms for __PACKAGE__.  Easier to type.

       $CLASS has the additional benefit of working in strings.

       CLASS - Alias for __PACKAGE__

       CLASS is a constant, not a subroutine call.  $CLASS is a plain variable, it is not tied.  There is no
       performance loss for using CLASS over __PACKAGE__ except the loading of the module. (Thanks Juerd)
