automatic currying in scheme

is it possible without macros?

((+) 1 2 3) ≡ ((+ 1) 2 3) ≡ ((+ 1 2) 3) ≡ (+ 1 2 3) ≡ (((+) 1) 2 3) ≡ (((+ 1) 2) 3) ≡ ...

i suppose that would really be some kind of laziness...

(define (plus . args)
  (if (null? args)
      plus
      (lambda x
        (apply plus (append args x)))))

this, unfortunately, never returns a value, only more functions

Yes. Partial application is when you apply a function taking n arguments to only one argument, and get a function taking n-1 arguments rather than a syntax error. Automatic currying is an ungainly way of saying it. But it has nothing to do with laziness.
