+For non-api methods (like `:add-foo` above), this map is the first argument before any arguments passed when calling the method using `react/call`.

 Modifying the `state` atom implicitly calls `this.setState`. The `refs` atom allows accessing `this.refs` as a map (e.g., `(.focus (.getDOMNode (@refs "my-text-box")))`).
 
 Note that `propTypes`, `statics`, and `mixins` are not yet implemented.
