/** File "LinkArg.h", by KWR for CSE250, Fall 2009.
    Argument for LinkTemplate<T>, but with a dreadful typo!
    Question: does YOUR compiler generate an error before linking?

    Also illustrates incoming and outgoing conversions, friending a function,
    and overloading a stream operator to emulate Java's implicit "toString()"
    Note that operator<< is not a member of the class, and (hence) is public.
    The code is also "const correct", including "const &" parameters.
