    you can use load-string or read-string. That's something like READ-FROM-STRING in common lisp, which adhere to the principle of 'Code is Data', treats the string as codes - evaluate and return the value.

    user=> (class (load-string "+"))
    clojure.core$_PLUS_
    user=> (read-string "+")
    +
    user=>
    

    then you can simply use it.
