What is the idiomatic way to obtain a sequence of columns from an incanter dataset?

What's the best way to get a sequence of columns (as vectors or whatever) from an Incanter data set? I thought of: (to-vect (trans (to-matrix my-dataset))) But Ideally, I'd like a lazy sequence. Is there a better way?
