Since let provides a lexical binding rather than a dynamic binding,
I'm not too surprised by the result.
Would the following do what you want?
(def ^{:dynamic true} *a* (fn [] "outside a"))
(binding [*a* (fn [] "inside a")] (load-string "(*a*)"))
(binding [*a* (fn [] "inside a")] (eval '(*a*)))
(FWIW, those yield "inside a" in both cases)
