I'd still rate Ben Cartwright's solution as the best. The one I posted
tried to do the same, but I didn't see the right way to iterate over
the supplied list inside the function, wheras he did. It's short,
simple and correct.

If you really wanted to return 'spam' or an exception in his solution,
it's a simple if statement at the start of the function.
