I would write that as [bindings & body] which is also recommended by

     `(let ~(vec (interleave names results)) ;;the new bindings

I would write that as `(let [~@(interleave names results)]

I personally prefer to not give intermediate values a name when they are 
only used in one place because it makes it easier to see that these values 
are only used in one place, but your mileage may vary. (Suggestive names 
can help readability, but in the end you have to read and understand what 
they refer to anyway)
