Don't need to ask if actions is an array

```sh
irb(main):001:0> def some(*actions)
irb(main):002:1>   actions.flatten
irb(main):003:1> end
=> nil
irb(main):004:0> some(1,2) == some([1,2])
=> true
irb(main):005:0> some(1,2) == some([[1,2]])
=> true
irb(main):006:0> some(1,2) == some([[1],[2]])
=> true
```
