How to include ambient module declarations inside another ambient module?

I have an ambient .d.ts module which directly depends on Immutable:

/// <reference path="../node_modules/immutable/dist/immutable.d.ts" />
import I = require('immutable');

declare module 'morearty' {
}

But referencing the immutable directly is prohibited by the compiler with this error:

error TS2435: Ambient external modules cannot be nested in other modules.

How could I include the Immutable ambient declarations inside my ambient module? I tried to import immutable from another proxy module but with no luck.

Ambient external modules cannot be nested in other modules.

Using an import or export at the root of a file creates a file module. That explains the error nested module.

Fix: Import inside and not at the root of the file: 

/// <reference path="../node_modules/immutable/dist/immutable.d.ts" />

declare module 'morearty' {
    import I = require('immutable');
}
