const numbers = [1, 2, 3, 4, 5]
R.filter(numbers, or(eq(1), eq(3), eq(5))) // => [1, 3, 5]

// Real-world: Filter by multiple statuses
const orders = [
  { id: 1, status: 'pending' },
  { id: 2, status: 'shipped' },
  { id: 3, status: 'delivered' },
  { id: 4, status: 'cancelled' }

  (o) => or(
    eq('pending'),
    eq('shipped')
  )(o.status)
) // => pending and shipped orders
