Io (http://www.iolanguage.com http://www.iolanguage.com) is a bit of an exception then. Its homoiconic but its not a Lisp. And it doesn't have macros yet its code is fully inspectable/modifiable at runtime in an very easy & elegant way. For eg. if you wanted to have a line like this: list(1, 2, 3) each foo bar which needs to be transformed into below at runtime: list(1, 2, 3) foreach(foo bar) Then this can be done like so: List each := method( m := call message m setName("foreach") setArguments(list(m attached)) setAttached(nil) self doMessage(m) ) ref: http://www.iolanguage.com/blog/blog.cgi?do=item&id=86 http://www.iolanguage.com/blog/blog.cgi?do=item&id=86
