with new UnitValue<T> we can now simplify some other types

export type UnitValue<T> = T extends Unit<infer V> ? V : never
export type StoreValue<T> = UnitValue<T>
export type EventPayload<T> = UnitValue<T>
export type EffectParams<FX extends Effect<any, any, any>> = UnitValue<FX>
export type EffectResult<FX extends Effect<any, any, any>> = UnitValue<FX['doneData']>
export type EffectError<FX extends Effect<any, any, any>> = UnitValue<FX['failData']>

Cool, thanks! 👍

I found that StoreValue should throw type error when used with events, so this is not an alias, as we previously thought
