Great suggestions! I like both of the solutions that are based on objects ({ recursive: x }).

I think I like the look of z.resource('orgs', 4, 'sub_orgs', { recursive: true }) best, but it does present a new risk for programmer mistakes. Consider the following code:

const retrievePerson = (person) => {
  // Expects person to be an ID
  return z.resource('orgs', 1, 'people', person);
};

// Passing an object, WITH and ID
retrievePerson({
  id: 1857,
  first_name: 'Clara',
  last_name: 'Zetkin',
});

The code contains a mistake. Instead of passing an ID, it passes an object which contains an ID. There would be no way for the SDK to detect that this was a mistake, because the object will be interpreted as a query object, and the request will be made to /orgs/1/people?id=1857&first_name=Clara&last_name=Zetkin instead of /orgs/1/people/1857 as was probably intended.

Do we consider this a problem? What do you think @niklasva82?

I also think that syntax is the most attractive. I understand the issue but I also don't think it will be a major one. If a programmer does this by mistake, then it simply won't work. I will implement something like this proposal.
