How to author a typescript module definition so that it exports a module dependency as its member?

Please consider the following scenario: I am attempting to author typescript definitions for two commonJS modules, A and B. B has a dependency on A, and, for convenience, B exports A directly as a property B.A so that the user does not need to explicitly require('A') in their code.

My question is, how can I author the typescript definition of B so as to export A as a property of B? Here is what I have attempted:

A has various members which it exports:

export const foo = 'bar';

Then, in B I have tried:

import * as A from 'A';
export A;

and

import * as a from 'A'; 
export var A : a;

However, neither of these are valid typescript module definitions.

The goal is, in the typescript code which is consuming B, to be able to write:

import B = require('B');
console.log(B.A.foo);

What is the correct way to author B's module definition so that it exports A as a property of B?

A.ts

export let foo = 1;

B.d.ts

import * as A from "./A";

export {
    A
}

usage

import B from "./B";

console.log(B.A.foo);
