Currently if you have the following file m1.ts

export default function Decl() {
    return 0;
}
export interface Decl {
    p1: number;
    p2: number;
}
export namespace Decl {
    export var x = 10;
    export var y = 20;
    interface I {
    }
}

trying to import m1.ts with a default binding will not give you all meanings of the exported entity:

import Entity from "m1"
Entity();
var x: Entity; // error
var y: Entity.I; // error
Entity.x; // error
Entity.y; // error

Discussed this with @JsonFreeman and @vladima, will try to elaborate more, but this issue should serve as a discussion point for suggestions, since there are certain interesting cases like non-exported uninstantiated namespaces.
