Ahh thanks! I forgot about that. I'm guessing I didn't think about it because I'm used to the following pattern ,which is actually useful from time to time in my projects. And typically it happens in an object/class:

  this[expr ? 'method1' : 'method2'](args)

So I have to add "this" as the methods are not global. Now if I overlooked something again I'm definitely getting rusty :)

Yes, that's better, especially since we do it elsewhere. Thanks!
