Re: Ruby and OO (fwd)

I'd like to point out that what makes the Ruby syntax convenient is that
it does not force the programmer to think in OO terms.  Even if the
block { |i| puts(i) } is implemented as some kind of object, from the
programmer's perspective it's just a function.  There's no need to
establish a package/object/method/statement/expression hierarchy as in

Here's complete code that gets rid of the scary word, "lambda", allowing

 (list-each lst (i) (puts i))

to work.  Any Scheme implementation that complies to the 1998 standard
will handle it.

(define (puts i)
  (display i)

(define-syntax list-each
  (syntax-rules ()
    ((list-each lst args expr ...)
     (for-each (lambda args expr ...) lst))))

(define lst (list 1 2 3))

(define (test-list-each)
  (list-each lst (i) (puts i)))
