Just some nitpicking: `curry' is the action of taking a function of
2 arguments and turning it into a function of one arg that returns another
function that expects the second arg.  I.e. (in pseudo Lisp):

     (curry 'concat)
     => (lambda (x) (lambda (y) (concat x y)))

     (funcall (curry 'concat) "The ")
     => (lambda (y) (concat "The " y))

     (mapcar (funcall (curry 'concat) "The ") '("a" "b" "c"))
     => ("The a" "The b" "The c")

I do not mean to say that you should change your `curry' to behave
differently, but just that the name `curry' is not quite correct for your
use (although your operation is definitely related to currying).

What your `curry' does is a combination of curry and function application,
which results in a partial function application.  Maybe we should call it
`partial-funcall'?
