One of the authors here. Thanks for the insight. I generally agree with the fact pretending it's like a local function will cause trouble down the track. After all, you're introducing a number of extra failure modes. The client library however does give some protections to the developer through the type system - although it's not perfect. Hence the wording "feel like". It's not actually local function calls. But it abstracts away a lot of the complexity.
