for (i=0; i < 10; i++) {
  openTabs.push(i);
}

var selector = Reselect.createSelector([
  function(obj) {
    return obj;
  }
],
  function(obj){
	return obj.get(7);
  }
);

selector(openTabs); // gotta cache the value before running the test!

Tests:

openTabs.get()
openTabs.get(7);

selector(openTabs);
