Hi Ken,
Just wrapping your macro with the following would save you the trouble of
having to enumerate the local variables ...
(defmacro eval-with-local-bindings [sexp]
`(eval-with-local-vars ~(apply vector (keys &env)) ~sexp))

That was really neat ken ... eval-with-local-vars.. I think it should be
part of the core...

Caveat: since eval-with-local-vars is a macro you won't be able to
directly use it in HOFs. Wrapping it in a closure works, however:
user=> (let [a 1 b 2] (map #(eval-with-local-vars [a b] %) ['(+ a b) '(* a b)]))
(3 2)
