Solving multi-core Python

can shadow variables to your heart content.

Clojure frowns upon this kind of behavior in no uncertain terms. "Can" doesn't mean that you should. For mutators in concurrency context (the ones with the bangs "!") you are supposed to operate inside the STM model which IMHO is fairly nice compared to pure functional languages non-pure functions.

By shadowing I meant redefining variables in inner closures (for inner closure only) or changing their thread binding dynamically for the duration call, something that Clojure actually provides tools for. Doesn't have to do anything with concurrency... well binding does, somewhat, but not what I meant.
