Namespaced aliases lost in translation

[Schahen]

While converting

declare var _: _.StaticInstance;
export = _;

declare module _ {
    type PropertyShorthand = string | number;

    interface StaticInstance {
        fetch<T>(param: _.PropertyShorthand): T[];
    }
}

StaticInstance converts to:

external interface StaticInstance {
    fun <T> fetch(param: `_`.PropertyShorthand): Array<T>
}

While PropertyShorthand is (ha!) lost in translation.

An other example, quite shameful one as well

declare module a {
  function ping(a: b.AlphaNumeric);
}

declare module b {
  type AlphaNumeric = string | number
}

export = a.ping
