Hah, I admit I lacked perseverance in looking at this in PyCharms debugger as I
missed
that.
Much appreciated!

Hah, I fired it in PyCharm's debugger and spent a wack time myself, thanks

You guessed correctly, and thanks for pointing out the ambiguity in my
references.

When you say "class vars", do you mean variables which hold classes? Like
