Comment 9 for bug 2047713

Thank you, this is exciting progress!

For #1, I will pull your latest updates and come up with an example that flows well.

For #2, either method works fine for me as long as the functionality is there. I'm still a Python novice; is this effectively the same as the constructor/function approach but with a bit more wrapper code to subclass them?

For #3, how about ElementFilter? I agree that "selector" has a CSS connotation that could blur the mental model and cause confusion. And, we already use the term "filter" in the BS4 documentation for this functional area.
