This explicit slice won't work, because a slice of a fixed size array results in a fixed size array.
There's no reason to allow this buggy code though. Also programmer didn't necessarily mean it. It could be a typographic error or a result of refactoring. Even if programmer wanted to write invalid code, what for? Yet this particular code doesn't need to be allowed to allow writing invalid code: one can still cast a number to pointer and do whatever he wants.
