The documentation for "has_many" reads: 
        Class->has_many(method_to_create => "Foreign::Class");

[download]
This method declares that another table is referencing us (i.e. storing our primary key in its table). It creates a named accessor method in our class which returns a list of all the matching Foreign::Class objects. In addition it creates another method which allows a new associated object to be constructed, taking care of the linking automatically. This method is the same as the accessor method with ``add_to_'' prepended.
The syntax that you reference has this to say:
Sometimes we don't want to return an instance of the Foreign::Class, but instead the result of calling a method on that object. We can do this by changing the Foreign::Class declaration to a listref of the Foreign::Class and the method to call on that class.
Which I don't fully comprehend.
