Title: Using ko.computed with a function returns readonly computed

I want readonly observables for my project, but the current definition for a computed returned from the
(func: () => T, context?: any, options?: any): KnockoutComputed; overload is like an observable:
(): T;
(value: T): void;

Supplying a value in this case will always throw an error, so I'd like to be explicit about it.
