Based on the spec, it would: 1. Import only push! and pop! from "stack," then 2. Import all identifiers from "stack" with the stack: prefix, then 3. Import all identifiers from "stack" again, except for clear!, which is renamed to empty!. The net result would include push!, stack:push!, stack:clear!, empty!, etc. -- almost certainly not what you meant. If I understand correctly, that's not even legal, since it imports some identifiers more than once. Instead of importing "stack" multiple times with different modifiers, I think you're supposed to nest the modifiers, with "stack" at the innermost point, i.e.: (import (add-prefix (rename (only "stack" push! pop! clear!) (clear! empty!) stack:))) This version will: 1. Start with all identifiers from "stack." 2. Narrow the list to only push!, pop!, and clear!. 3. Rename clear! to empty!. 4. Apply the stack: prefix to all three names. It avoids repetition of the "stack" and more precisely states how to perform the namespace modifications. I think the result is a bit obscure, although I would expect few programs to actually combine all three modifiers like this. -- Bradd W. Szonye http://www.szonye.com/bradd
