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.
