Immediately creating Stub replacement is deprecated

[jonathan-benn]

var stub = sinon.stub(object, "method", func);
# This has been removed from v3.0.0. Instead you should use
# stub(obj, 'meth').callsFake(fn)

Do you want to remove this 3-argument version of sinon.stub?

It's doable, and the modification is like CALLQUEUE removal.

I prefer to keep both, I don't think there is any big reason for completely removing this. (The implementation is same, but with different interface + a bridge function.

[jonathan-benn]

I agree, it's better to keep both

Some opinion about implementing callsFake(fn):

1. using unwrap function
2. using wrap2stub function again

When solving this issue, keep in mind the following interesting property from Sinon.JS (basically, the replacement function becomes the default, but it can still be overridden by e.g. withArgs):

o = {func: function(x) {return x*2;}}
stub = sinon.stub(o, 'func').callsFake(function(x) {return 'Hello World!';})
stub.withArgs('A').returns('Arg of A')
stub() // "Hello World!"
stub('A') // "Arg of A"
stub.returns(5)
stub() // 5
stub('A') // "Arg of A"
