This inspection reports any instances of 'fallthrough' in a switch statement. 'Fallthrough' is defined to occur when a series of executable statements after a switch label is not guaranteed to transfer control before the next switch label. In that case, control 'falls through' to the statements after that switch label, even though the switch expression does not equal the value of the fallen-through label. While occasionally intended, this construction is confusing, and is often the result of a typo.
