Repro:

user=> (require '[sci.core :as sci])

;; in JVM Clojure:
user=> (alter-var-root #'*file* (constantly "duuude1"))
"duuude1"
user=> (defn foobar [])
#'user/foobar
user=> (:file (meta #'foobar))
"duuude1"
user=> (alter-var-root #'*file* (constantly "duuude2"))
"duuude2"
user=> (defn foobar [])
#'user/foobar
user=> (:file (meta #'foobar))
"duuude2"
