> Some things that would be convenient when notated implicitly make thinking about other things difficult. This really comes out in math, where choice of notation can call attention to different aspects of a concept. The Wikipedia page for ordinary least squares, for example, freely intermixes (depending on how you count) 3 or so different styles of notation. I think that this is why I've always been fascinated by Knuth's literate programming. If you want to make something more understandable, saying it twice in two different ways is a great technique.
