I think, sadly, I have to -1 on this one. It does not clear when I see this
method what would happen when you pass in array with multiple elements, or when
the array unexpextedly have moret than one element. Assume that that array will
always has 1 element is ... Not a good idea.
I think it's already clear and make sense to just call .first or [0] on it.
Since you would be like "I don't care how many things it has in it, I want the
first one."
