Symbol-functions, as much as I sometimes wish for them, aren't a great idea: They give macro-writers even less guarantees. However, wrapping datastructures in functions definitely is. Also, first-class environments are amazing, and I wish my scheme-of-choice (CHICKEN) had them: It used to, but the code doesn't work with the new compiler, and the long-promised replacement hasn't been written yet. Maybe I should just dive in and write it myself...
