Object detection for "Exported variable `` has or is using name `` from external module"

[Deathspike]

With the following structure:

• node_modules/a/default.d.ts containing a typing and a function
• node_modules/a/package.json containing a typings field to default.d.ts
• src/default.ts' re-exporting everything from a and exporting new functions
• src/newFunctions.ts using the src/default.ts

You get "exported variable has or is using name from external module" errors when using an object:

import * as b from './default';

// Bug: This does the same thing, but in an object. It should still compile fine, but it doesn't.
export let wrap = {
  findPersonById: function(id: number): b.IPerson {
    return b.findPersonById(id);
  }
}

However, when you don't use an object the functionality works as expected:

import * as b from './default';

// OK: Expected behavior. Since `b` exports everything from `a`, exporting `b.IPerson` is fine.
export function wrapFindPersonById(id: number): b.IPerson {
  return b.findPersonById(123);
}

A simplified repro is available in #8612

#8612 is what I'm trying to do. What is the difficulty of fixing this issue? Or, is there any way to work around this so that all the exports from a group of files can be imported into the same namespace?
