A few API changes:
Remove Callback in favor of directly using closures or JsFunction.withThis().
Move jsify() to a named constructor on JsObject.
- Throw on types other than Map and Iterable.
- Handle cycles
Add JsObject.fromDartObject() which force a transferrable native to be proxied.
Still to do: Reach a conclusion on Serializable

-/**
- * The js.dart library provides simple JavaScript invocation from Dart that
- * works on both Dartium and on other modern browsers via Dart2JS.
- *
- * It provides a model based on scoped [JsObject] objects. Proxies give Dart
- * code access to JavaScript objects, fields, and functions as well as the
- * ability to pass Dart objects and functions to JavaScript functions. Scopes
- * enable developers to use proxies without memory leaks - a common challenge
- * with cross-runtime interoperation.
- *
- * The top-level [context] getter provides a [JsObject] to the global JavaScript
- * context for the page your Dart code is running on. In the following example:
- *
- * import 'dart:js';
- *
- * void main() {
- * context.callMethod('alert', ['Hello from Dart via JavaScript']);
- * }
- *
- * context['alert'] creates a proxy to the top-level alert function in
- * JavaScript. It is invoked from Dart as a regular function that forwards to
- * the underlying JavaScript one. By default, proxies are released when
- * the currently executing event completes, e.g., when main is completes
- * in this example.
- *
- * The library also enables JavaScript proxies to Dart objects and functions.
- * For example, the following Dart code:
- *
- * context['dartCallback'] = new Callback.once((x) => print(x*2));
- *
- * defines a top-level JavaScript function 'dartCallback' that is a proxy to
- * the corresponding Dart function. The [Callback.once] constructor allows the
- * proxy to the Dart function to be retained across multiple events;
- * instead it is released after the first invocation. (This is a common
- * pattern for asychronous callbacks.)
- *
- * Note, parameters and return values are intuitively passed by value for
- * primitives and by reference for non-primitives. In the latter case, the
- * references are automatically wrapped and unwrapped as proxies by the library.
- *
- * This library also allows construction of JavaScripts objects given a
- * [JsObject] to a corresponding JavaScript constructor. For example, if the
- * following JavaScript is loaded on the page:
- *
- * function Foo(x) {
- * this.x = x;
- * }
- *
- * Foo.prototype.add = function(other) {
- * return new Foo(this.x + other.x);
- * }
- *
- * then, the following Dart:
- *
- * var foo = new JsObject(context['Foo'], [42]);
- * var foo2 = foo.callMethod('add', [foo]);
- * print(foo2['x']);
- *
- * will construct a JavaScript Foo object with the parameter 42, invoke its
- * add method, and return a [JsObject] to a new Foo object whose x field is 84.
