Hmmm, I presume you meant:

   (defmacro rcurry (f &rest args)
     `(curry rcurry-helper f (list ,@args)))

But I think given the way the implementation works, just including the
dividing point as an integer would be faster (can use bcopy instead of
list traversal) and consume less space overall (a vector slot for each
arg is cheaper than a cons cell for each).
