Immobservable?

immobservable.js

import mobservable from 'mobservable/immutable' // Separate module needed?
                                                // Not sure, but basically we need 
                                                // to mark it as immutable somehow

let user = mobservable.fromJson({ 
  name: 'Matt',
  age: 'NunYoBiznis'
})

user.name //= 'Matt'
user.name = 'Matthew' // ignored
user.name //= 'Matt'

mobservable.transaction(() => {
  user.name = 'Matthew' // applied
  user.name //= 'Matthew'
})

I love the mechanisms and simplicity of observers, but sometimes it'd be nice to have some simple -- I hesitate to use the term 'immutability', since that carries some baggage, but frankly -- immutability. :-)

For systems (or teams) of a certain size, it becomes useful to be able to strictly control where mutations can occur (usually in a controller/flux store).

How would this work? Well I'm not exactly sure, but my naive idea is that any setter created by the immutable observable would check for some sort of inTransaction flag and only do the update and trigger the change if it's true.
