Source docstring:

Generic assertion macro.  'form' is any predicate test.
'msg' is an optional message to attach to the assertion.

Example: (is (= 4 (+ 2 2)) "Two plus two should be 4")

Special forms:

(is (thrown? c body)) checks that an instance of c is thrown from
body, fails if not; then returns the thing thrown.

(is (thrown-with-msg? c re body)) checks that an instance of c is
thrown AND that the message on the exception matches (with
re-find) the regular expression re.

(defmacro is
  ([form] `(cljs.test/is ~form nil))
  ([form msg]
   `(try-expr ~msg ~form)))
