Clojure: just return the value

Question

Is there any Clojure built-in function that just returns the value being passed to it? The equivalent of ``` (defn just-val [x] x) ``` ?

Accepted Answer

Yes there is the identity function: http://clojuredocs.org/clojure_core/clojure.core/identity

```
user=> (identity 4)
4
```
