External modules with AMD always requires "exports" even when it is not used

Here's a small external module that explicitly exports a module:

module Foo {
    export var foo = 42;
}
export = Foo;

The code generated for this is:

define(["require", "exports"], function(require, exports) {
    var Foo;
    (function (Foo) {
        Foo.foo = 42;
    })(Foo || (Foo = {}));

    return Foo;
});

This feels like bad AMD since you are requiring the "exports" magic dependency, but then not using it and instead returning Foo directly.

It's annoying for minimal AMD loaders since they can't assume the object return of your module is your "exports" object and have to guess that you really meant to return something that overrode the "exports" object you asked for.

Furthermore, why bother declaring a dependency on 'require' when it's not used?

Beginne damit, das Problem anhand des TypeScript-Beispiels zu reproduzieren und die generierte AMD-Ausgabe zu vergleichen. Untersuche den Emissionspfad des Compilers für AMD external-module und, falls vorhanden, dessen Regressionstests. Als erledigt gilt die Aufgabe, wenn ungenutzte "require"- und "exports"-Abhängigkeiten nicht emittiert werden, während der zurückgegebene Modulwert korrekt bleibt.
