Title: Knockout overwrites computed observable

Hi,

When you bind an input element to a computed it appears that knockout simply overwrites the computed with the input's value.

I think it is preferable that knockout throws an exception - similar to "Cannot write a value to a ko.computed unless you specify a 'write' option".

Thanks.
