=head1 DESCRIPTION
This pragma is very similar to the C<Class::props> pragma: the main
difference is the underlying variable that holds the value, which is
a global scalar in the caller package instead in the class. For example:
package BaseClass;
use Package::props 'a_package_prop';
use Class::props 'a_class_prop';
package SubClass;
our @ISA = 'BaseClass';
# underlaying scalar for accessor 'a_package_prop' is
# $BaseClass::a_package_prop
# underlaying scalar for accessor 'a_class_prop' is
# $SubClass::a_class_prop;
This might seem a subtle difference, but the possible usage in inherited classes
makes a big difference.
You can also call a package property accessor by statically using the implementing
package name (e.g. C<BaseClass->a_prop>), regardless the subclass that uses it.
See the documentation of the accessor properties in L<Class::props>
for all the details.
