    if (typeof keyComparer === "function") keyComparer = Comparer.create(keyComparer);
    assert.mustBePossiblyAsyncOrderedIterable(source, "source");
    assert.mustBeFunction(keySelector, "keySelector");
    assert.mustBeComparer(keyComparer, "keyComparer");
    return FlowHierarchy(ThenByAsync(ToAsyncOrderedIterable(source), keySelector, keyComparer, /*descending*/ false), source);
