However, it is possible to take this idea too far. In a module for network communication, a student team masked all network exceptions: if a network error occurred, the module caught it, discarded it, and continued as if there were no problem. This meant that applications using the module had no way to find out if messages were lost or a peer server failed; without this information, it was impossible to build robust applications. In this case, it is essential for the module to expose the exceptions, even though they add complexity to the module’s interface. With exceptions, as with many other
