it should be possible to redefine a computed property

[mweststrate]

Example;

const a = observable({
  width: 10, 
  get surface() { return this.width }
})

observe(a, "surface", v => console.log(v))
reaction(() => a.surface, v => console.log(v))

extendObservable(a, {
  get surface() { return this.width * 2 }
})

Should no longer throw but work as expected.

Downside: there might be issues with lingering low-level subscriptions, the above observe based logger will keep listing to the 'old' definition (which is the reason it is now forbidden). Normal property access like the reaction should work correctly. Potential confusion about the difference is the reason it has not been supported so far
