Exception for space-before-keywords?

Writing a React/redux app, I am occasionally declaring anonymous classes inside function calls:

``` javascript
export default connect()(class extends Component {
// React component class definition
});
```

which gives this error: `Missing space before keyword "class". (space-before-keywords)`.

If I put a space there:

``` javascript
export default connect()( class extends Component {
// React component class definition
});
```

It fails another rule: `There should be no spaces inside this paren. (space-in-parens)`.

Was wondering if that was an unintended effect of the `space-before-keywords` or if everything is working as expected.

Start by reproducing the reported anonymous class example with the project's ESLint rules, then inspect how space-before-keywords and space-in-parens are configured. Done means the project has a decided, documented behavior for this syntax and the corresponding rule configuration or test demonstrates it.
