That's a solution to find the first matching item.
But that's not the only reason to loop through a list.
"else" would be a general purpose solution.

That's, well, elegant! Yes.
Because and but it's tricky.
Nothing where I'd say "wow, thats an easy solution to my problem!".
It's a bit complicated, because you have to understand and combine
several concepts. That's elegant. But not easy, I think.
I think it's not simple enough for this simple kind of problem.
