How to drive a "dirty" flag i.e. for all edits, set some global isDirty=true?

[res63661]

We have the need in literally every store that we create to be able to bind the ux to some value that turns true as soon as the state is mutated in some way. This includes nested complex objects. It is not Clear to me what the best practice should be for this I've tried several different things including subscriptions but with the limited success. How to do this In a lean efficient manner without overloading the system computationally?

ex:
Given some store:

{
...

state = ()=>({
person: { name: "Fred", id: "lkjh-1234-2-432-1234432"},
isDirty: false,
...
})
...
}

Assume we make some edit as follows:
store.person.name = "Wong"
//store.isDirty now == true

We now need our save buttons to enable across our application. So we want to bind to store.isDirty

How to achieve this?
