I'm quite familiar with currying, but in the context of Elisp it's
rather tricky to give a good and reliable specification of what it
should do. E.g. what should (curry #'apply) or (curry #'list) return?
So, I think we can't magically handle all cases.
Of course, we can do the easy cases:
(defun curry (f n)
(if (< n 2)
f
(lambda (x)
(curry (apply-partially f x) (- n 1)))))
but ... I'm not sure we want to encourage this.
What's your use case(s)?
Stefan
