## E0072: methods should not use the 'function' keyword

Classes and object literals can contain methods. It is an error to use the `function` keyword in a class or object literal when defining a method:

    class Doge {
      function speak() {
        console.log('many woofie');
      }
    }

To fix this error, remove the `function` keyword:

    class Doge {
      speak() {
        console.log('many woofie');
      }
    }
