Maybe we can get it a little more Clojure-ish:

    (dosql [a :table1/a b :table1/b]
      (filter (and (< a 5) (= b "x"))))

Makes the filter part more readable (to a Lisper), and introduces variable scope in a more idiomatic manner. The macro needs to take care of the :table1/a expansion and substitution within its scope. dosql might already be taken but not important for my point, I think.

Maybe you still don't like this, but I think it reads a little better for someone used to Clojure.
