... it's not? I was just providing an authoritative reference for the parent's claim.

(Pedantic note: It's technically incorrect to say that the switch statement does nothing.

    switch(FunctionThatDoesSomethingAndReturns1()) {
        case 2:
            // foo
    }
The switch body does nothing, but the actual statement does something.)
