Re-export submodule

[unional]

file1.ts

export function A() {}
export function B() {}

Currently, if I want to export file1.ts as a sub module, I have to do:
file2.ts

import * as subModule from "./file1.ts";

export var subModule = subModule;  // or,
export { subModule }

Is there an easier way such as:

export { * from subModule } from "./file1.ts"

Would it be ES6/ES7 compatible I didn't see any sample regarding this usage.

One question need to solve is how to handle any default export in the sub module.

Recommended

export * from "./file1.ts"

or an even older syntax (pre es6):

export import subModule = require('./file1.ts');

Note : They are not exactly equivalent 🌹

there is an ES7 proposal for this: https://github.com/leebyron/ecmascript-more-export-from#proposed-additions

Once this reaches Stage 3, TypeScript will need to support it.

i have filed #4813 to track this work.
