When I first ran into the problem with (-) and sections, I was slightly annoyed with having to write (+ (-1))

Let's not forget that there is the library function 'subtract' for this purpose. What you wrote could be written as (subtract 1), which is more readable in my opinion. But hey, what do I know, I think using the underscore for unary negation (à la Emacs calculator) would be an acceptable enough compromise. -- -David House, dmhouse@gmail.com
