Class inheritance

Inheritance in Perl is handled through the @ISA array – module names appearing in the array are taken as classes from which we can inherit additional methods. With Python the process is more explicit – you list the classes from which you want to inherit at the time you define the class. For example if you want the class Citrus to inherit from the class Fruit:

class Citrus(Fruit): ...

The actual list of classes to inherit values from can be as long you like so that:

package Recipe; @ISA = qw/Fruit Vegetable Meat DryGoods/;

is equivalent to the Python:

class Recipe(Fruit, Vegetable, Meta, DryGoods):
