### What it does

Disallows anonymous functions and classes as default exports.

### Why is this bad?

Naming default exports improves searchability and ensures consistent
identifiers for a module’s default export in both declaration and import.

### Examples

Examples of **incorrect** code for this rule:

```javascript
export default class {}
export default function () {}
export default () => {};
module.exports = class {};
module.exports = function () {};
module.exports = () => {};
```

Examples of **correct** code for this rule:

```javascript
export default class Foo {}
export default function foo () {}

const foo = () => {};
export default foo;

module.exports = class Foo {};
module.exports = function foo () {};

const foo = () => {};
module.exports = foo;
```

## How to use

## Version

This rule was added in v0.3.3.
