Make it possible to export namespaces

[Swatinem]

Currently re-exporting namespaces creates invalid code, because of the way that rollup handles these things.

It would be good to research if it is even possible at all to solve this usecase.

import * as ns from "./namespace";

export { ns };

Other things that don’t work correctly which are related to namespace imports:

export type T = typeof import("./bar")

I think the only way to solve this is to do some post-processing of the bundle that rollup generates…

This is the code that rollup generates:

interface A {
}
declare function b(): void;
declare class C {
}
var namespace = /*#__PURE__*/Object.freeze({
	A: A,
	b: b,
	C: C
});
export { namespace as ns };

I think something like this should work as the final result:

interface _A {}
declare function _fn(): void

declare namespace ns {
  export { _A as A, _fn as fn }
}

export { _A as A, _fn as fn, ns }
