The competent programmer is fully aware of the strictly
        limited size of his own skull; therefore he approaches the
        programming task in full humility, and among other things he
        avoids clever tricks like the plague.  In the case of a
        well-known conversational programming language I have been
        told from various sides that as soon as a programming
        community is equipped with a terminal for it, a specific
        phenomenon occurs that even has a well-established name: it is
        caled "the one-liners."  It takes one of two different forms:
        one programmer places a one-line program on the desk of
        another and either he proudly tells what it does and adds the
        question, "Can you code this in less symbols?"---as if this
        were of any conceptual relevance!---or he just says, "Guess
        what it does!"  From this observation we must conclude that
        this language as a tool is an open invitation for clever
        tricks; and while exactly this may be the explanation for some
        of its appeal, viz., to those who like to show how clever they
        are, I am sorry, but I must regard this as one of the most
        damning things that can be said about a programming langauge.
