Should we add a helper?

http://emberjs.com/api/classes/Ember.Helper.html#sts=Ember.Helper%20Class%20packages/ember-htmlbars/lib/helper.js:8

One thought that comes to mind is how we would reconcile naming between the component's already have and the helpers to do the same thing.  Maybe if really only make sense to use them if `{{if}}`s then could name them `if-able` and `if-unable`.
