A book of this high quality probably shouldn't mis-use lay & lie.

On page 155 you have:

"Clojure is partially a lazy language. This is not to say that Clojure vectors lay around the house everyday after school playing video games and refusing to get a job."

It's "lie" in this case. The mnemonic my editor wife taught me is "lions lie, chickens lay." Your lazy vector is lying around like a lion, not laying around like a chicken!
