    type Item = {
        name: string;
        ...
        size?: string;

I'm not really following how this would avoid `name: "grande latte"`?

But then the example response:

    "size": 16

Is it? It's not even returning the type being asked for?

I'm guessing this is more of a typo in the example, because otherwise this seems cool.
