It is up to the reader to decide if that increases or decreases maintainability :)

On the one hand, I really like how there are so many similarities with shell scripting, in terms of syntax at least. On the other, it's a bit confusing to keep track of so many implicit behaviors. I was always told to be explicit whenever possible as it makes code easier to reason about. I'm afraid to forget what variables like @_ do if I don't use them often enough! :D

Thanks for the tips!
