Manual Reference Pages - DBM::DEEP::NULL (3)
DBM::Deep::Null - NULL object
This is an internal-use-only object for DBM::Deep. It acts as a NULL object
in the same vein as MARCELs Class::Null. I couldnt use Class::Null
because DBM::Deep needed an object that always evaluated as undef, not an
implementation of the Null Class pattern.
It is used to represent null sectors in DBM::Deep.
