Crafty Closure for Retaining Scope

var FeedCat = function () {
    this.cat = 'Garfield';
    
    this.feed = function (scope_) {
        var scope = scope_;

        var feedIt = function (food) {
            scope.doFeed(food);
        }

        return feedIt;
    }(this);
}

FeedCat.prototype.doFeed = function (food) {
    console.log('Feeding '+this.cat+' '+food+'.');
}
    
var feedingTime = new FeedCat();
feedingTime.feed.call(this, 'lasagne');
