Creating an object

To create an object of class Foo::Bar, one would write:

    $object = Foo::Bar->new();

This calls the "new" function you defined in package Foo::Bar.  The arrow notation tells Perl to mutate the class name into the first argument position, where it is used to bless an empty hash reference into a "Foo::Bar" object.

You now have an empty hash reference with a funny name.
