Decorators not allowed classes expressions

Not sure if this is by design or not, but the following gives a compile error of “Decorators are not valid here” with TypeScript 1.8:

let testClass = new class {
    testMethod(@myDecorator date: Date): any {
        return date;
    }
}();

This also applies when using the new 2.2 mixin design.

I.e.

/** Any type that can construct *something*. */
type Constructor<T> = new (...args: any[]) => T;

function ViewModel<T extends Constructor<MyModel>>(Base: T) {
	return class extends Base {

                // Won't compile. Decorator not allowed here
		@observable
		IsReadOnly: boolean;

                // Won't compile. Decorator not allowed here
		@computed get SomeProp(): string[] {
			return []
		}

		constructor(...args: any[]) {
			super(...args);
			this.IsReadOnly = true
		}
	}
}

Is this something that should work?

they were never enabled for class expressions. so the behavior has not changed. but they should.
