        What a programmer is full of after fixing the last bug and
        just before actually discovering the *next* last bug.  Fred
        Brooks's book "{The Mythical Man-Month}" contains the
        following paragraph that describes this extremely well.
     
        All programmers are optimists.  Perhaps this modern sorcery
        especially attracts those who believe in happy endings and
        fairy god-mothers.  Perhaps the hundreds of nitty frustrations
        drive away all but those who habitually focus on the end goal.
        Perhaps it is merely that computers are young, programmers are
        younger, and the young are always optimists.  But however the
        selection process works, the result is indisputable: "This
        time it will surely run," or "I just found the last bug.".
