Exporting a method in a class in ES2015

I'm trying to export the toString method alone but it's failing. The first export is working fine but the other one I added is failing.

class Point {
  constructor(x, y) {
    this.x = x;
    this.y = y;
  }
  toString() {
    return `(${this.x}, ${this.y}`;
  }
}

export {Point as XPoint}; // this is working great

but this is failing

export {Point.prototype.toString as PointToString};

What is the proper export syntax for exporting specific method in a class?

Here is the error that webpack is saying:

ERROR in ./es6/Point.js Module build failed: SyntaxError: /Users/demouser/repos/webpack-es6-demo/es6/Point.js: Unexpected token (12:13)

You can only use identifiers inside of export specifiers:

const PointToString = Point.prototype.toString;
export { PointToString }

See: http://www.ecma-international.org/ecma-262/6.0/index.html#sec-exports
