what would it take to be able to provide nested objects for params?

[faceyspacey]

I'm essentially looking to be able to POST complex JSON.stringified objects. Looking at the objective C code there is a "todo" to add support for objects. I'm no expert in objective-C, I can't even tell if it supports anything but strings, i.e. numbers. What would it take to make the params parameter similar to what you would pass for the body parameter in fetch, or perhaps the non-stringified version as that seems to be its direction?
