Understood. Thanks for clarifying. I think Chris was referring to this in
an earlier message (when I made my first attempt at translating) when he
said:

So the meaning of my translation matches the "intention" of the original
PEP 505 expression, but I see the danger in offering up such loose
translations. Getting the meaning right but missing important details (like
repeated evaluation) does not inspire confidence.
