E0073: missing function parameter list

Functions declared with function can have zero or more parameters. It is a syntax error to omit the parameter list, including ( and ), even if the function has no parameters:

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

function visitDogPark {
  new Doge().speak();
}

setInterval(
  function {
    visitDogPark();
  },
  1000,
);

To fix this error, add a pair of parentheses before { in the function:

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

function visitDogPark() {
  new Doge().speak();
}

setInterval(
  function() {
    visitDogPark();
  },
  1000,
);

Introduced in quick-lint-js version 0.2.0.
