This smells like an XY problem [0]. Why exactly do you need the 
internal layout of the array structure?

The line "not having to make another array to keep track of 
lengths and then shorten them" is fairly vague. "Shortening" an 
array via slicing is basically free (it's just some integer 
arithmetic), but I'm not sure if that's what you meant.
