index.d.ts type BoundAction: Expected 0 arguments, but got 1.

Line 9 in 1df7cf6

export type BoundAction = () => void;

I'm looking into use cases for Unistore where I need to expose the store and bound actions for use in other frameworks. I've been taking advantage of store.action() to get a handle on that bound action, but I get typing issues when that action takes parameters due to how BoundAction is defined.

For example when I...

      // define the action as an unary function
      const actions = {
        toggleLoading: (_state: MyState, isLoading: boolean) => ({ isLoading })
      }
      // and then get the bound action from our previously created store
      const toggleLoading = store.action(actions.toggleLoading) 
      // I receive:  TS2554: Expected 0 arguments, but got 1.

I have temporarily sidestepped this issue by locally redefining BoundAction to be:

export type BoundAction = (...args: any) => void;

I'm a TypeScript newbie so I don't have good sensibilities when it comes to typing yet. Is there a 'better' way to type this, or am I doing something wrong?

Thanks!

@reallyely I've implemented your workaround in 6e26e4b for now. I think there is probably a hacky way to get types to propagate here, but TypeScript doesn't have support for mixing Generics with variadic arguments, so it'd basically be listing out the possible argument types manually (gross).
