[Bug] Unclear default export

[Wayofthesin]

Given the file:

export default class MyClass {
    // MyClass implementation
}

The parsed File object has following declarations:

[
    DefaultDeclaration: {
        isExported: true,
        exportedDeclaration: self
    },
    ClassDeclaration (MyClass): {
        isExported: false
    }
]

Expected:

• ClassDeclaration.isExported to be true
• DefaultDeclaration.exportedDeclaration to be MyClass declaration
