Seems quite non-obvious to me why does UnwrapArray actually panic in this case...

@YuriyNasretdinov The problem in unwrap1 function:

const stringLenBytes = 4

func unwrap1(s string) (one string) {
	return s[stringLenBytes+1:] // do not care about length, there is only 1 param
}

if we have "null" string, then we will have slice from 5, but we have only 3 indexes. we can modify unwrap1 function to return empty string if len(s) > stringLenBytes+1, but we are talking about "types" and "null" is a special type that`s why i think we should add condition in logic of LazyArrayElemType. What do you think?

Thanks for the explanation. I think it makes sense now. BTW I am not a maintainer of the project (but I was at some point), so I'm just being curious :).
