DBM::Deep::Null
This is an internal-use-only object for "" in DBM::Deep. It acts as a NULL object in the same vein as MARCEL's "" in Class::Null. I couldn't use "" in 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.
To install DBM::Deep, copy and paste the appropriate command in to your terminal.
cpanm
cpanm DBM::Deep
CPAN shell
perl -MCPAN -e shell install DBM::Deep
