This is the reason that I prefer a lot of lattitude in Scheme syntax. There are forms that no human would write but that are marginally legitimate and might be generated by a macro. It is painful to try to make every part of a complex macro expand into well-written code. -- ~jrm _________________________________________________ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/dev
