Should there be support for a .frozen property?

I found myself in the need to test if an object was frozen.

Right now, one has to do:

expect(Object.isFrozen(obj)).to.be.true;

which is not very pretty. I came up with a simple helper to allow the following syntax:

expect(obj).to.be.frozen;

I am not sure if this helper should be part of this project. On one end, it's not using Immutable, but on the other end, Object#freeze() is the closest we have to immutable objects in JS...

So, should I include it here? Any other suggestion?

yes, would be handy

Alright, it's on the todolist then :-)

Well... I did it, and then I un-did it because it has just been added to Chai 3.1.0.

Please use this assertion then. Makes more sense to find it there anyway!
