If you were to say, (macroexpand '(foo)), it returns (foo), even if it's not defined in the context, so I'd say it's a little unexpected.
More annoying is the result this has on macroexpand-all, which breaks because of this weird behaviour: (use 'clojure.walk) (walk/macroexpand-all '(let [Object (fn [])] (Object))) java.lang.RuntimeException: java.lang.Exception: Expecting var, but Object is mapped to class java.lang.Object (NO_SOURCE_FILE:0) Of course, this example is somewhat (not super-) obvious, but in more complex cases it could be fairly annoying.
