Get ECMAScript 5 Intellisense in Visual Studio

Are there any known solu开发者_JS百科tions to supporting ECMA 5 features in Visual Studio's Intellisense?

For example, it would be nice to have Object.create() and Object.defineProperty() as well as all of the new methods and functions on the native types.

I tested the developer preview of Visual Studio 11, and much of ECMAScript 5 is supported by Intellisense. I don't see solutions for support in VS 2010, so I guess the answer is: Wait for VS 11.
