would be great to have this - do you have any ideas on how to supply types for the returned setters? Because they are dynami 'set' + prop.name it can be quite the challenge I would imagine.

Yeah, it's pretty much done. Unfortunately, TypeScript doesn't have an API that lets you dynamically compose object property names. There's an open feature request for it since 2016: microsoft/TypeScript/issues/12754

I see, I was thinking something like this might be good enough, at least all properties of the setters would be functions then:

export default function useMultiState<T>(initialState: T): [T, (newState: Partial<T>) => void, { [key: string]: Function }];

I'll send a PR if you want

Sure, go ahead!
