Yeah, that was my conclusion too, and `scribble/html' does just that (actually it inherits it from `scribble/text'). BTW, another minor disadvantage with xexprs is that you need a separate rendering pass if you want to have references such as a TOC. The `scribble/html' thing allows promises and thunks which makes it easier to deal with. -- ((lambda (x) (x x)) (lambda (x) (x x))) Eli Barzilay: http://barzilay.org/ Maze is Life! _________________________________________________ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/dev
