DBM::Deep::Null - NULL object

       DBM::Deep::Null - NULL object

       It is used to represent null sectors in DBM::Deep.

perl v5.36.0                                       2023-11-12                               DBM::Deep::Null(3pm)

       This is an internal-use-only object for DBM::Deep. It acts as a NULL object in the same vein as MARCEL's
       Class::Null. I couldn't use Class::Null because DBM::Deep needed an object that always evaluated as
       undef, not an implementation of the Null Class pattern.
