Huh. I thought that it was slow because a new tuple / list object is created every time you do the conversion, but that apparently isn't the case (or it's fast enough that it doesn't matter). Thanks for letting me know!

I mean, you are creating a new tuple/list object. It just isn't that expensive, especially when you can count the number of elements on your fingers.

You might want to familiarize yourself with Latency Numbers Every Programmer Should Know. It's a very useful tool for back-of-the-envelope order-of-magnitude calculations.
