How about a withPropTypes? about recompose

Or actually... you'd have to create a new component to avoid mutating state and actually use the return value, right? Like:

const withPropTypes = curry((propTypes, BaseComponent) => React.createClass({
     propTypes,
     render() {
          return <BaseComponent {...this.props} />;
     }}));

Good idea. In 0.6.0 I've added a set of static helpers, including one called setPropTypes(), which works essentially the same as the version in your original comment.

Since propTypes are only useful during development, I don't think it makes sense to wrap the base component in a new component, so this actually mutates the base component.

Thanks for the suggestion!

Awesome, the implementation looks great. Thanks!
