But you would still have to catch the exception. Not a nice thing to 
terminate the program just because an expected mismatch occured.

Not finding something is not exceptional.

Neither is EOF on a file, or working with an empty list. Adding all these
exceptions for non-exceptional and quite common scenerios is bothersome.
