It may be an alternative, but it breaks the principle of least surprise. If I'm
looking through someone's code, and I see a switch, I expect to see it used as
Jim described. If the writer needs a different type of logic to make a
decision, that is what the cascaded if-elseif-elseif construct is for, when the
tests don't fall into a simple set-of-values choice.
The job of a programmer is not to be "clever" with a view to impress those who
follow, but to achieve the desired outcome while at the same time making life
easy for those who follow.
