What is the current behavior?

Currently we can only pass selector functions to createSelector arguments

Expected behavior:

It would be useful to be able to pass an array of selectors to an argument of createSelector, which will return two values for the next selector in the composition

Minimal reproduction of the problem with instructions:

From: https://github.com/reactjs/reselect#composing-selectors

const getKeyword = (state) => state.keyword

const getVisibleTodosFilteredByKeyword = createSelector(
  [ getVisibleTodos, getKeyword ],
  (visibleTodos, keyword) => visibleTodos.filter(
    todo => todo.text.includes(keyword)
  )
)

Most selectors take in one argument (usually the state), but in some cases a selector can take 2 or more arguments, composing an array of selectors can help to form the number arguments for the next selector.
