Clojure compile issue

Why the following code cann't pass compilation?

(defn testit [asym] (var asym))

The error is:

CompilerException java.lang.RuntimeException: Unable to resolve var: asym in this context, compiling:(NO_SOURCE_PATH:1)

asym there is not a var, it's a local; in this case, the sole argument to the function that you're defining as the value of the testit var.

If you want to return asym from that function:

(defn testit [asym] asym)

If asym is a symbol that names a var you want to return, then use resolve:

(defn testit [asym] (resolve asym))

General note: (var x) is the expanded special form corresponding to the reader syntax #'x.
