DBM::Deep::Null3pm
Null object
Purpose
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.
Overview
It is used to represent null sectors in DBM::Deep.
