Thanks, that's exactly what I meant, and you're absolutely correct--it 
isn't a true map, even if it is occassionally useful. Perhaps it would be 
better to leave it out; a fold would probably be sufficient. (I use Chez, 
and Chez doesn't have fold, so I end up using map. But fold would do.)

Yes: think a bit more about the philosophy and apply it a bit more 
consistently (all the way down to parameter order).
