Specify circular associations in an AMD context like require.js

reverseRelationTest_js_House.js

define([
    "backbone.associations",
    "Person"
], function(Associations, Person){

    var House = Backbone.AssociatedModel.extend({
        relations:[{
            key:"person",
            type:Backbone.One,
            relatedModel: function(){ return require("Person");}
        }]
    });

    return House;
})

reverseRelationTest_js_Person.js

define([
    "backbone.associations",
    "House"
], function(Associations, House){

    var Person = Backbone.AssociatedModel.extend({
        relations:[{
            key:"house",
            type:Backbone.One,
            relatedModel: function(){ return require("House");}
        }]
    });

    return Person;
})

Thanks - @mattcroberts

Quick question - why do we need to load the required module again in the relatedModel function? If instead we had

relatedModel: House,

wouldn't that still work as a closure?
