Yow. I've just read PEP309, which (to my shame) I hadn't
done when reading your original comment. I thought I could
tell from your comments how PEP309 was using the term
"currying".
I was completely wrong; I misunderstood what you were
protesting about, and I now agree: PEP309 misuses the term
"curry".
