Constant vs Dependencies

[FredLackeyOfficial]

In the "cc-bmean" demo (not sure about the others) why did you bring in toastr and moment as constants (in constants.js) rather than listing them in the module's dependencies list when it was declared?

/* global toastr:false, moment:false */
(function () {
    'use strict';

    angular
        .module('app.core')
        .constant('moment', moment)
        .constant('toastr', toastr);
})();
