No, eval is a simply a function and so like any other function it can't
"see" the lexical (local) environment which it was called from.
Doing this:
(let [a 1, b 2] (eval '(+ a b)))
Is similar to doing this:
(defn cake []
(+ a
This works as I would expect it to.
'rule' brings in 'state' from the global binding into it's scope
giving it priority over the outer scope bindings found in the parent
function.

It seems to be intended, if undocumented* and sometimes awkward, behavior.
* In that (doc eval) doesn't say anything about this issue.
