Perl version >= 5.6.1

From the directory where this file is located, type:
perl Makefile.PL make make test make install
This pragma is very similar to the Class::groups pragma: the main difference is the underlying variable that holds the value, which is a global hash in the caller package instead in the class. For example:
Class::groups
package BaseClass; use Package::groups 'a_package_group'; use Class::groups 'a_class_group'; package SubClass; our @ISA = 'BaseClass'; # underlaying hash for accessor 'a_package_group' is # %BaseClass::a_package_group # underlaying hash for accessor 'a_class_group' is # %SubClass::a_class_group;
This might seem a subtle difference, but the possible usage in inherited classes makes a big difference.
While you can also call a package group accessor by statically using the implementing package name (e.g. BaseClass-a_group>), regardless the subclass that uses it, overridden package accessor groups don't inherit defaults as Class accessors do.

See the documentation of the accessor groups in Class::groups for all the details.
