Well, if you look at the annotated source code, you'll find that set does a lot.

What if you extended Backbone.Model with a function that does it for you:

Backbone.Model.prototype.setByName = function(key, value, options) { 
    var setter = {}; 
    setter[key] = value; 
    this.set(setter, options); 
};

Then, you can just do what you want directly on the model:

var model = new Backbone.Model();
model.setByName(myProperty, "bar");

That feels like a better solution to me.

Edit

As @earl3s pointed out, this is no longer necessary in more recent versions of Backbone. Today, you can just call model.set(myProperty, "bar") and it does what you want.
