[] is not a function in JavaScript. It's a property access. a[b] equates 
to a.b (leaving the type and possible values of 'b' aside).

With the regular QObject slot and property based approach you might not be 
able to model such a random index access. But how about you implement a 
thin wrapping layer in JavaScript? Through __defineGetter_ you should be 
able to forward property access attempts to a C++ slot internally.
