Repeat doesn't; the above repeat function will return a sequence of empty vectors, not a sequence of empty sequences. The ones that iterate over a collection turn the iterated-over arguments into a sequence: all but repeat and iterate. Still only those arguments: for instance, map won't apply "seq" to its function argument. :) Their outputs are all lazy sequences.
