PropTypes for stateless components. Would be great If static keyword inside function block - is a link to function object (constructor). So we can write as at the first example.

stateless-static-props-inside-function.js

export default (props) => {
  // this is not possible, but I think this is  more readable that next example
  static propTypes = {
    name: PropsTypes.string.requried  
  };
  
  return <Div>{props.name}</Div>;
}

stateless-static-props-outside-function.js

const Name =function(props) {
  return <Div>{props.name}</Div>;
}

Name.propTypes = {
  name: PropsTypes.string.requried  
};

export deafult Name;

Which example is better and more readable?)

static props/methods definition available only for classes
