Lisp has that for many operators and comparisons: (+ x1 x2 x3 x4),
(< x1 x2 x3 x4), and so on. I certainly have never heard that this
was considered a mistake in the lisp community. But then, because of
lisp's syntax, there is no parsing problem here at all.


I would be interested in knowing which other problems you have thought
or heard of, in particular, is the code hard to understand because of
the parsing problems (for the programmer), or are there other issues
involved?
