changing dependentObservable() function, to enable chained writes

[shoky]

Hi

I've found out (thanks to this forum) that for computed observables, it's not possible to chain writes like this:

viewModel.someComputed(20).otherComputed(100).someObservable('hi')

and this bummed me because I have many observables which I now want to extend - so they will become computed,

and so I have to remove all the chained calls.

So I've made this small change in the dependantObservable() function (just added: return this;)

    function dependentObservable() {

        if (arguments.length > 0) {

            set.apply(dependentObservable, arguments);

            return this;

        } else {

            return get();             

        }

    }

And now I can chain writes!

My question is: what's the downside of doing this?

I assume there is one, because this wasn't implemented :P

Thanks,

Uri G
