    I think I prefer "lispy" iteration macros.  Here is an example of what I
    mean by a lispy iteration macro:

    ;; Return a list of the items in list-of-items 
    ;; which pass the test TEST.
    (iterate ((item in list-of-items))
      (when (test item)
	(collect item)))

Parens do not a Lisp code make.  This particular example, for instance,
isn't any "lispier" than the equivalent LOOP construction; the
expression "(collect item)" is CERTAINLY not a call to some new function
COLLECT, is it?
