Disallow unnecessary namespace qualifiers.

🔧

Some problems reported by this rule are automatically fixable by the --fix ESLint command line option.

💭

This rule requires type information to run.

Members of TypeScript enums and namespaces are generally retrieved as qualified property lookups: e.g. Enum.member. However, when accessed within their parent enum or namespace, the qualifier is unnecessary: e.g. just member instead of Enum.member. This rule reports when an enum or namespace qualifier is unnecessary.
