anchor.diff:  WARNING: cljs.core/+, all arguments must be numbers, got [string] instead at line 1 <cljs repl>
   ----
   
  -`clj-nil` is no longer considered a numeric type, so, for example `(+ nil 1)` will warn
  -
  -Incorrect function with fixed arity of more params than variatic now causes a
  -warning. For example:
  -
  -----
  -cljs.user=> (defn foo ([x] 1) ([& xs] 2))
  -WARNING: foo: Can't have fixed arity function with more params than variadic function in file <cljs repl>

   ## Performance Improvements
   
   * `re-pattern`, `re-matches`, and `re-find` are now faster
  
positive.code: 
  ### Iterator Support
  
  It is now possible to `seq` on any object implementing JavaScript's
  Iterator protocol. A new core predicate, `cljs.core/js-iterable?`
  is introduced with this feature.
