Hey, just dropping in to say: the moment I saw the demo of the feature, I said to myself, "that's gonna be due to a good underlying data structure and this article is going to be about that data structure".

Was not disappoint.

This is a lesson I learned way too late in IT: Get the data structure right and interesting features come at reduced cost.

Put an interface around it and you can change the underlying data structure.

Except for when you can't, because all abstractions leak.

Of course there are always times where you can't.

But most of the times you can.
